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

Solution

## The correct option is A polymerization of ethene in a hydrocarbon solvent in the presence of Ziegler-Natta catalystMethod 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 $$333 K$$ to $$343 K$$ and under a pressure of $$6-7$$ atmosphere,The correct option is $$[A]$$.ChemistryNCERTStandard XII
