Abstract
Process for making a polymer and the resultant polymer wherein polymer particles, preferably those having a core and a shell structure, most preferably wherein the core comprises polybutadiene and the shell comprises polymethylmethacrylate, are included in metathesis polymerizable mixtures to provide the resultant polymer with improved resistance to oxidation and greater retention of mechanical properties upon thermal aging, and to toughen the resultant polymer.
