Some Condensation Polymers The difference in Tg and Tm between the first polyester (completely aliphatic) and the two nylon polyamides (5th & 6th entries) shows the effect of intra-chain hydrogen bonding on crystallinity. Buna-S, Buna-N. 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. 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. Example of copolymerization is the process of forming polymer Buna-S from 1, 3-butadiene and styrene. Classification Based on Monomers. Example: Buna-S, Buna-N, etc. Question 60: Identify the four groups into which the polymers are classified on the basis of the magnitude of intermolecular forces present in them.

It is inert to most chemicals with the exception of fluorine and molten alkali metals. Condensation Polymer:-The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. Condensation polymerizations, as the name suggests, utilizes bond-forming reactions that generate a small molecule condensate, which often needs to be contin-uously removed to facilitate the formation of the polymer. Be the first to write the explanation for this question by commenting below.. Related Questions: • When these monomers react, small molecules such as water are lost 2.
