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.
