Polymerisation of vinyl cyanide with peroxide catalyst forms _______ a) PVC b) PAN c) PET d) HDP

Polymerisation of vinyl cyanide with peroxide catalyst forms _______

a) PVC

b) PAN

c) PET

d) HDP

Expert Solution

Answer : b) PAN

Explanation :

Polyacrylonitrile (PAN) is a polymerised product of acrylonitrile (vinyl cyanide) in the presence of a peroxide (H2O2) catalyst.

Acrylonitrile --------> PAN

Vinyl cyanide can be prepared by treating ethyne with HCN in the presence of Ba(CN)2 catalyst.

C2H2 + HCN -----> Vinyl cyanide

PAN is used for making orlon and acrilan. PAN is chemically inert.

b) PAN
