ABSTRACT:
Excellent and very high quality impact-resistant polymer products products are comprised of particular polyether elastomer constituents which modify and attribute many desirable properties and characteristics to the interpolymerized end product; impact styrene polymers being especially advantageous varieties thereof. In-situ polymerization, with specific coordination catalyst systems, is followed to form polyether polymers of epoxidized monomer constituents provided directly dissolved (or dispersed) in the major addition-polymerizable monomer utilized. The rubbery polyether elastomer so made is then interpolymerized with the major monomer to provide the advantageous high impact end product.
