Abstract
Compositions which have substantial weatherability and impact resistance include a substantially uniform blend of an acrylonitrile/styrene/acrylic polymeric material and a wood component in an amount effective as a filler in the composition. Methods for making such compositions include forming a substantially uniform physical mixture of such polymeric material and wood component.
Claims31
A weatherable composition comprising an acrylonitrile/styrene/acrylic polymeric material, an acrylic copolymer comprising a cross-linked alkyl acrylate/graft (meth)acrylate copolymer, the acrylate copolymer being present in an amount effective to enhance the impact resistance of the weatherable composition relative to a substantially identical composition without the acrylic copolymer, and a wood component in an amount effective as a filler in the weatherable composition.
A method for forming a weatherable composition comprising:
- (1) providing an acrylonitrile/styrene/acrylic polymeric material;
- (2) providing an acrylic copolymer comprising a cross-linked alkyl acrylate/graft (meth)acrylate copolymer;
- (3) providing a wood component;
- and
- (4) forming a weatherable composition of a substantially uniform physical mixture including said acrylonitrile/styrene/acrylic polymeric material, said acrylic copolymer, and said wood component, said acrylic copolymer being present in an amount effective to enhance the impact resistance of the weatherable composition relative to a substantially identical composition without the acrylic copolymer.
A weatherable composition comprising an acrylonitrile/styrene/acrylic interpenetrating interpolymer comprised of a crosslinked (meth)acrylate component, a crosslinked styrene-acrylonitrile component and an uncrosslinked styrene-acrylonitrile component, and a wood component in an amount effective as a filler in the weatherable composition.
A method for forming a weatherable composition comprising:
- (1) providing an acrylonitrile/styrene/acrylic interpenetrating interpolymer comprised of a crosslinked (meth) acrylate component, a crosslinked styrene-acrylonitrile component and an uncrosslinked styrene acrylonitrile component;
- (2) providing a wood component;
- and
- (3) forming a substantially uniform physical mixture including said acrylonitrile/styrene/acrylic interpolymer and said wood component.
