Abstract: IMPACT-RESISTANT POLYMERS WHICH HAVE LOW PERMEABILITY TO GASES AND VAPORS ARE PREPARED BY POLYMERIZING AN OLEFINIC NITRILE, SUCH AS ACRYLONITRILE, WITH A VINYL ETHER, SUCH AS BUTYL VINYL ETHER, TO AT LEAST ABOUT 50% CONVERSION, AND THEN INTRODUCING INTO THE POLYMERIZATION REACTION MEDIUM A CONJUFATED DIENE MONOMER, SUCH AS BUTADIENE-1,3, AND COMPLETING THE POLYMERIZATION REACTION IN THE PRESENCE OF SAID DIENE MONOMER.

Abstract: Interpolymers having high impact strength, high softening temperature and other excellent properties result from the polymerization of an olefinic nitrile such as acrylonitrile, a vinyl aromatic monomer such as styrene, and maleimide in the presence of a conjugated diolefin elastomer.
