Question

Classify the following as addition and condensation polymers giving
reason :
(a) Teflon
(b) PHBV
​

Answer 1

Answer:

Teflon comes under addition polymer , the structure of teflon is as follows

Teflon is polytetrafluoroethylene, or PTFE. The molecular structure of Teflon is based on a chain of carbon atoms, the same as all polymers. Unlike some other fluoropolymers, in Teflon this chain is completely surrounded by fluorine atoms. The bond between carbon and fluorine is very strong, and the fluorine atoms shield the vulnerable carbon chain.

PHBV stands for Poly(3-hydroxybutyrate-co-3-hydroxyvalerate),  this type of polymersbelong to the category of condensation polymer, it   is a polyhydroxyalkanoate-type polymer. It is biodegradable, nontoxic, biocompatible plastic produced naturally by bacteria and a good alternative for many non-biodegradable synthetic polymers. ... PHBV undergoes bacterial degradation in the environment.
