There are two types of Condensation polymers: 1. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. Condensation polymerisation. Both are formed differently, and have distinct structural features. View desktop site. D) Condensation polymers contain all of the atoms of the original monomers, but addition polymers do not. There are two major types of polymers: addition polymers and condensation polymers. Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE). Students can solve NCERT Class 12 Chemistry Polymers MCQs Pdf with Answers to know their preparation level. It is an inexpensive resin per unit weight. . Terms Condensation polymers are formed through a condensation reaction, where molecules join together, losing small molecules as byproducts. It is used as friction modifier. Polystyrene is a thermoplastic polymer. If both moieties are difunctional, the condensation product is a linear polymer, and if at least one of the moieties is tri- or tetra-functional, the resulting polymer is a crosslinked polymer Polyisoprene is a polymer of isoprene and is … *Addition polymerization -The addition polymerization means that two monomers react with each other and no other small molecules are generated. For e.g., Nylon - 6, 6 is formed by condensation polymerization of adipic acid and hexamethylenediamine. Polystyrene is made from the monomer styrene which is a liquid petrochemical. Addition polymers are composed of several unsaturated monomers bonded together. In the repeat unit In the repeat unit above shown the R … Examples: Nylon, terylene, Bakelite. © 2003-2020 Chegg Inc. All rights reserved. General-purpose polystyrene is clear, hard, and rather brittle. Because the ionic strength of urine is equivalent to an 0.1 M NaCl solution, this superabsorbant polymer, which can be found in disposable diapers, can absorb up to 60 times its weight in urine. Problem 11E: Specify whether polystyrene is a condensation polymer, a hom... JavaScript is required to view textbook solutions. Important condensation reactions are esterification, ester interchange, etherification, and amidization. Formation of the polyester terylene from a dicarboxylic acid (benzene-1,4-dicarboxylic acid) and diol (ethane-1,2-diol). POLYAMIDE Polyamides are a group of condensation polymers commonly known as nylon. Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer or a block polymer. Start studying Chem Homework Polymers. Dextron is a polyacetic acid polyglycolic acid polymer. Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer, or a block polymer. The process is known as condensation polymerisation - forming water molecules together with polyester molecules. Polystyrene is used in insulation and in molded items such as coffee cups. Polyesters such as PET (polyethylene terephthalate) are condensation polymers. & Condensation polymers are formed by the combination of monomers with the elimination of simple molecules such as H 2 O or CH 3 OH. The best example is polymerization of ethylene. These monomer units are linked to each other either through the formation of peptide linkage, glycosidic linkage or by removal of any moiety such as a water molecule. Answer/Explanation. Therefore, most polyurethane and polystyrene foams are manufactured by forcing a pressurized gas, such as nitrogen or carbon dioxide, into the polymerizing mixture. Chemistry MCQs for Class 12 Chapter Wise with Answers PDF Download was Prepared Based on Latest Exam Pattern. Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. The history of PUs started in 1937 when Dr Otto Bayer of Bayer Germany invented the diisocyanate polyaddition process. & Condensation Polymers The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. | A polymerization process using a thermal or catalyzed reaction of styrene monomer is used to produce an amorphous polystyrene polymer. 2. View desktop site. Polyamide. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Polyvinyl chloride (PVC) is extensively used for plumbing pipes. It becomes rigid again when it cools down. Polystyrene is an aromatic polymer and has many uses including protective packaging, in trays, as … Figure \(\PageIndex{4}\): Polyvinyl chloride. Privacy Protein is a natural polymer. Experimental Organic Chemistry | 6th Edition. DVB has vinyl groups (-CH=CH 2) at each end of its molecule, each of which can be polymerized into a polymer chain like any other vinyl group on a … Polystyrene is a hard, brilliantly transparent, stiff resin. HDPE is composed of macromolecules in which n ranges from 10,000 to … Privacy Polythene is a copolymer, while SBR is a homopolymer. a. You should be able to draw a short section of a polymer given the monomer units (and vice versa). Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer or a block polymer. Polystyrene with DVB: Cross-linking between polymer chains can be introduced into polystyrene by copolymerizing with p-divinylbenzene (DVB). Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat. It is produced by the polymerization of styrene and is the most widely used plastic. Figure \(\PageIndex{3}\): Polystyrene synthesis and structure. Polyester. Polyurethanes (PUs) are a family of condensation polymers that include the urethane (–NHCOO–) group in the chemical structure (Figure 5.1). The formation of a polyester follows the same procedure as in the synthesis of a simple ester. Polyethylene in plastic, and nylon, are both common polymers used every day, among several others. Answer. Notice that n monomer molecules produce one polymer molecule with n repeat units. Condensation polymer among the following is - (a) Teflon (b) Polystyrene (c) PVC (d) Dacron Novolac, the linear polymer used in paints is (a) copolymer of buta 1, 3-diene and styrene (b) polymer of methyl methacrylate (c) condensation polymer of phenol and HCHO (d) copolymer of melamine and HCHO. Bakelite is a condensation polymer of phenol and formaldehyde. Check Answer and Solution for above question from Chemistry in Polymers - Tardigrade Terms [For more information about this polymer, see Ibid., Volume 1, page 216.] Polystyrene can be solid or foamed. The monomers used are lactic acid and glycolic acid. Which of the following is a condensation polymer ? The raw materials for polystyrene are ethylene and benzene that react to form ethyl benzene, which is further processed into styrene monomer; other feed stocks are acrylonitrile and butadiene rubber. This polymer can absorb 800 times it own weight of distilled water, but only 300 times its weight of tap water. It is added to lubricants to reduce surface friction. The molecule most commonly split out between monomers to make a condensation polymer is -It requires two like molecules. Answer: c Explaination: (c) It … At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows. Free PDF Download of CBSE Chemistry Multiple Choice Questions for Class 12 with Answers Chapter 15 Polymers.

What is Bakelite? Polystyrene is … H2O. The synthesis of polystyrene is carried out using a reaction known as free radical polymerisation. Terylene: Example of polyester. Polystyrene b. Teflon c. Polyvinychloride d. polypropylene e. dacron In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers. Answer to Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer, or a block polymer. WBJEE 2018: A condensation polymer among the following is (A) Dacron (B) PVC (C) Polystyrene (D) Teflon. Styrene consists of a benzene ring (a six membered ring with three double bonds) bonded to an ethene chain. (A) Polystyrene (B) PAN (C) Neprene (D) Polyethyleneglycol terephthalate. In a polymer, the monomers are linked to each other in a continuous or repetitive manner. Neoprene is a natural rubber.
