Correct answer
B(a) (III), (b) (I), (c) (IV), (d) (II)
Step-by-step explanation
High density polythene is obtained by using
Ziegler-Natta Catalyst.
Polyacrylonitrile is obtained by acrylonitrile using peroxide catalyst.
Novalac is obtained by acid or base catalyzed polymerization of phenol.
Nylon–6 is condensation polymer which is made at higher temperature and pressure.
