Title: HDPE and LDPE
Post by: applesauce on February 22, 2018, 08:15:05 pm

hey could someone pls help me with this.

do both HDPE and LDPE use a organic peroxide initiator? the only difference is that HDPE uses a zeigler natta catalyst right?

The only difference is indeed that HDPE uses a Ziegler-Natta catalyst, and effectively speaking replaces the peroxide initiator. HDPE is still produced through initiation/activation, propagation and termination, but thanks to the Ziegler-Natta catalyst, the peroxide initiator is gone.
