Question

High density polythene is obtained by:

• A. polymerization of ethene in a hydrocarbon solvent in the presence of Ziegler-Natta catalyst
• B. polymerization of ethene under high pressure and temperature
• C. free radical polymerization of ethene at low-temperature polymerization peroxide
• D. polymerization of ethene in presence of carbon tetrachloride

Answer 1

The correct option is A polymerization of ethene in a hydrocarbon solvent in the presence of Ziegler-Natta catalyst

Method of the preparation of high-density polythene-

It is formed when addition polymerisation of ethene takes place in a hydrocarbon solvent in the presence of a catalyst such as triethylaluminium and titanium tetrachloride (Ziegler-Natta catalyst) at a temperature of $333K$ to $343K$ and under a pressure of $6-7$ atmosphere,

The correct option is $\left[A\right]$.
