Vedclass · Answer

(A) Condensation polymers are formed by the repeated condensation reaction between two different bi-functional or tri-functional monomeric units,usually with the elimination of small molecules like $H_2O$,$HCl$,etc.Bakelite,Nylon $6$,and Nylon $6,6$ are all examples of condensation polymers.Buna-$N$ is formed by the copolymerization of $1,3$-butadiene and acrylonitrile in the presence of a peroxide catalyst. It is an addition polymer,not a condensation polymer.
