Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat. The monomers used are lactic acid and glycolic acid. The only difference is that both the alcohol and the acid monomer units each have two functional groups - … What is Bakelite? Neoprene is a natural rubber. Answer/Explanation. Polystyrene can be solid or foamed. Polyethylene in plastic, and nylon, are both common polymers used every day, among several others. Free PDF Download of CBSE Chemistry Multiple Choice Questions for Class 12 with Answers Chapter 15 Polymers. Notice that n monomer molecules produce one polymer molecule with n repeat units. [For more information about this polymer, see Ibid., Volume 1, page 216.] -It requires two like molecules. It is added to lubricants to reduce surface friction. Condensation polymers are formed through a condensation reaction, where molecules join together, losing small molecules as byproducts. WBJEE 2018: A condensation polymer among the following is (A) Dacron (B) PVC (C) Polystyrene (D) Teflon. Polystyrene with DVB: Cross-linking between polymer chains can be introduced into polystyrene by copolymerizing with p-divinylbenzene (DVB). Condensation polymers are formed by the combination of monomers with the elimination of simple molecules such as H 2 O or CH 3 OH. Important condensation reactions are esterification, ester interchange, etherification, and amidization. View desktop site. 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. Privacy Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE). Specify whether polystyrene is a condensation polymer, a homopolymer, a copolymer, or a block polymer. 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. POLYAMIDE Polyamides are a group of condensation polymers commonly known as nylon. Examples: Nylon, terylene, Bakelite. It becomes rigid again when it cools down.
