Q.38. Which among the following statements is NOT true for LDP?
A. It needs O2 or peroxide as initiator synthesis process.
B. It is a branched chain polymer.
C. It needs low pressure about 6-7 atm in synthesis process.
D. It has low melting point than HDP.
Answer :- C. It needs low pressure about 6-7 atm in synthesis process
Explanation :-
LDP is prepared by polymerization of ethylene under high pressure (1000−2000 atm) and temperature (350−570 K) in presence of traces of O2 or peroxide as initiator.
