The correct match between Item - and Item -
is :
Item - I | Item-II | ||
(a) | Highest density | (I) | Peroxide catalyst |
(b) | Polyacrylonitrile | (II) | Condensation at high temperature & pressure |
(c) | Novolac | (III) | Ziegler-Natta Catalyst |
(d) | Nylon 6 | (IV) | Acid or base catalyst |
(a) High-density polyethene (III)Ziegler-Natta catalyst
(H.D.P)
H.D.P is obtained by using Zigler-Natta Catalyst
(b) Polyacrylonitrile (I)Peroxide catalyst
Polyacrylonitrile is obtained by using the peroxide catalyst
(c) Novolac (IV) Acid or base catalyst
It is obtained by acid /base Catalyst polymerisation of formaldehyde & phenol.
(d) Nylon 6 Condensation at a high temp. & pressure.
At high T &P, it is condensation polymer of caprolactam
