PROCESS FOR ENHANCING THE MELT STRENGTH OF POLYPROPYLENE(CO)POLYMERS
摘要
The invention pertains to a process for enhancing the melt strength of a polypropylene(co)polymer with the aid of initiator dispersions. The use of initiator dispersions with a particulate initiator instead of the corresponding non-dispersed initiators or their dilutions or solutions results in a significant enhancement of the melt strength of the modified polymer, and a wide range of initiators turn out to be serviceable.
