Example of copolymerization is the process of forming polymer Buna-S from 1, 3-butadiene and styrene. Nylon-6,6 or Nylon-6 is an example of condensation polymer. Addition Polymers • Each monomer has two of the same functional groups. Nevertheless, the polymer clearly forms by a step-growth process. MCQs Of Polymer chemistry 1. Preparation: butadiene (about 75% by weight) and styrene (25% by weight) co-polymerize to give styrene butadiene rubber (SBR) as follows-The products formed by copolymerization show the specific properties of the monomers and hence is very useful in industry. Condensation polymers: Terylene, bakelite. (A) Nylon-66 (B) PTFE (C) Dacron (D) Glyptal. Condensation polymers are formed by condensation of two or more bifunctional monomers with the elimination of simple molecules like H 2 O, NH 3, alcohol, etc. Condensation polymers are formed by polycondensation, when the polymer is formed by condensation reactions between species of all degrees of polymerization, or by condensative chain polymerization, when the polymer is formed by sequential addition (by condensation reaction) of monomers to an active site in a chain reaction. A hydrogen moves from the alcohol to the nitrogen, while the oxygen links to the carbon. The formation of copolymer Nylon 6, 6 is from adipic acid and hexamethylenediamine.

Classification Based on Molecular Forces Polymers can also be classified on the basis of mode of polymerisation into two sub groups. Technically polyurethane is not a condensation polymer since no molecules are lost, but the functional group does rearrange. A few ‘crosslinks’ are introduced in between the chains, which help the polymer to retract to its original position after the force is released as in vulcanised rubber. Condensation Polymers These polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. Condensation Polymers 1.
