Answer» Correct option (2) (a) → (III), (b) → (I), (c) → (IV), (d) → (II) Explanation: Nylon –6 is condensation polymer of capzalocatiom at higher temp and presser. Novalac is obtained by acid or base catalyored polymerization of phenol and termaldehyde high-density plythere is obtained by using Ziegler natta catalyst. Polyacrylonitrile is obtained by acrylonitrile using peroxide or catalyst. |
