摘要： The present invention relates to high melt swell partially neutralized alpha olefin acid copolymers. It also relates to a process for making such high melt swell polymers as well as for covalently crosslinking other polar copolymers including non-neutralized acid copolymers and non-polar alpha olefin polymers by using a minor amount of metal acrylate, particularly sodium or zinc acrylate.
