Q. The catalyst used in the polymerization of high density polythene is
A) Titanium oxide
B) Titanium isoperoxide
C) Lithium tetrachloride and triphenyl aluminium
D) Titanium tetrachloride and trimethyl aluminium
Explanation
(d)
High density polythene is obtained, when ethane undergoes Ziegler-Natta polymerisation. In this process, Ziegler-Natta catalyst, a mixture of titanium tetrachloride $(TiCI_{4})$ and trimethyl aluminium $\left\lbrack \left( CH_{3} \right)_{3}Al \right\rbrack$ is used to catalyse the polmerisation.
