Abstract
Materials which have substantial weatherability and impact resistance include a substantially uniform blend of an acrylonitrile/styrene/acrylic (ASA) polymeric material, a wood component in an amount effective as a filler, and a vinyl chloride polymeric material. Methods for making such compositions include combining a first population of pellets comprising an ASA polymeric material and a wood component, and a second population of different pellets comprising a vinyl chloride polymeric material.
Claims21
A process for producing an extrudable composition useful in forming a shaped product comprising:
- providing a first population of pellets comprising a first composition comprising an acrylonitrile/styrene/acrylic polymeric material and a wood component;
- providing a second population of pellets having a different composition than the first population of pellets and comprising a second composition comprising a vinyl chloride polymeric material;
- and
- combining a portion of the first population of pellets and a portion of the second population of pellets to form a combination of pellets that is extrudable into a shaped product other than pellets.
A composition, comprising
- a first population of pellets comprising a first composition comprising an acrylonitrile/styrene/acrylic polymeric material and a wood component, the first population of pellets formed by a process comprising extruding and pelletizing the first composition;
- and
- a second population of pellets comprising a vinyl chloride polymeric material, having a different composition than the first population of pellets and being substantially free of wood, the second population of pellets being combined with the first population of pellets to form a combination of pellets that is extrudable into a shaped product other than pellets.
