In the manufacture of polythene by the Ziegler process using ethene, the temperature for proper polymerisation required is
Open in App
Solution
The correct option is C
High density polythene is formed when addition polymerisation of ethene takes place in a hydrocarbon solvent in the presence of Ziegler-Natta catalyst at a temperature of 333 K to 343 K and under a pressure of 6-7 atmospheres.
