The catalyst used in the manufacture of polyethene by Ziegler method is
1 Titanium tetrachloride and triphenyl aluminium
2 Titanium tetrachloride and trimethyl aluminium
3 Titanium dioxide
4 Titanium isopropoxide
Explanation:
The catalyst used in the manufacture of polyethylene high-density polythene by Zeigler-Natta method is \(TiCl _4\) (titanium tetrachloride) and \(\left( C _2 H _5\right)_6 Al _2\) (triethyl aluminium).

Ethylene-propylene rubber (\(EPR\)) is
1 Unsaturated, stereoregular
2 Saturated, stereoregular
3 Atactic, unsaturated
4 Syndiotactic, unsaturated
Explanation:
It’s Obvious.

Acetate rayon is prepared from
1 Acetic acid
2 Glycerol
3 Starch
4 Cellulose
Explanation:
(d) Rayon fibre is chemically identical to cotton but has a shine like silk, rayon is also called a regenerated fibre because during its preparation. Cellulose is regenerated by dissolving it in \(NaOH\) and \(C{S_2}\).
