(A) Orlon is a commercial name for polyacrylonitrile $(PAN)$.It is prepared by the addition polymerization of acrylonitrile $(CH_2=CH-CN)$ in the presence of a peroxide catalyst.The reaction is as follows:$n(CH_2=CH-CN) \xrightarrow{\text{Polymerization}} [-CH_2-CH(CN)-]_n$Thus,Orlon fibres are made up of polyacrylonitrile.
