Abstract
A molding composition having improved toughness and impact strength comprising 60-90 percent by weight of a matrix resin in the form of a polyester or polyamide resin, reacted with 40-10 percent by weight of a rubber formed by copolymerization of ethylene, one or more mono-olefins, and preferably one or more polyenes, and an ester of an alpha, beta-unsaturated acid having an epoxide functionality on the alkoxy portion. The composition is prepared by forming a masterbatch containing the backbone rubber, a monomer having the epoxide functionality, a catalyst and a portion of the matrix resin of the final composition in a single step bulk process, and thereafter blending the masterbatch with the remainder of the matrix resin.
