More Information
Summary:The invention provides a process to form a second composition comprising a modified ethylene-based polymer, the process comprising the step of contacting under thermal treatment conditions a first composition comprising a first ethylene-based polymer, and the following: (A) at least one carbon-carbon (C-C) free radical initiator; and (B) at least one free radical initiator other than a C-C free radical initiator of (A) (a non-C-C free radical initiator). The melt strength of the second composition is typically at least 15% or greater than the melt strength of the first composition. The second composition typically has a gel content less than or equal to 40.
