Patent ID: 8846824

Claim:
An impact modified polymer alloy composition consisting of: a) one or more functional polymers selected from the group consisting of polyethylene terephthlate (PET), polyamides, glycol modified polyethylene terephthlate (PETG), natural polymers, carbohydrates, cellulose, biopolymers, polylactic acid, and polyhydroxy butyrate, b) one or more non-functional polymers selected from the group consisting of alkyl (meth)acrylate polymers and copolymers, acrylonitrile/butadiene/styrene terpolymers (ABS), acrylonitrile/styrene/acrylate copolymers, polycarbonates, methacrylate/butadiene/styrene copolymers, polystyrene, acrylonitrile/acrylate copolymers, acrylonitrile/methyl methacrylate copolymers, poly(vinyl chloride), a homopolymer of a vinylidene halide, and alloys thereof; wherein the ratio of functional polymer to non-functional polymer is from 20:80 to 80:20, and c) functional core-shell impact modifier, wherein the outer-most shell comprises from 0.5 to 30 weight percent, based on the shell polymer, of functional groups including at least glycidyl(meth)acrylate, and the core comprises one or more polymers selected from the group consisting of styrene-butadiene, butadiene, and methacrylate-butadiene-styrene, and optionally d) non-functional additives selected from the group consisting of glass beads, polymer beads, glass fibers, carbon nanotubes, and pigments.
