Abstract
This invention relates to polyolefin alloys that are receptive to metal plating. These compositions also have enhanced properties and are easily processed into articles by various molding methods. The blends of the invention preferably include polyolefin homopolymers or copolymers, acrylonitrile-butadiene-styrene polymers, and a blend of at least one styrene monoolefin copolymer and at least one styrene diolefin copolymer. These blends have excellent platability and superior physical properties including enhanced rigidity, toughness, and dimensional stability.
Claims21
A platable polyolefin blend comprising the following components:
- a propylene-containing polymer formed from a semi-crystalline homopolymer of propylene or a copolymer of propylene with ethylene or an alpha olefin;
- a polymeric compatibilizer comprising at least one styrene monoolefin copolymer and at least one styrene diolefin copolymer, wherein the combined styrenic copolymers are present in an amount sufficient to facilitate adhesion between the components of the polyolefin blend;
- and
- an ABS resin component of an acrylonitrile-butadiene-styrene resin or a blend of styrene-acrylonitrile resin with a diene, the ABS resin component being present in an amount sufficient to render the polyolefin blend suitable for electroplating.
A process for preparing a plated polyolefin article which comprises:
- blending a propylene-containing polymer formed from a semi-crystalline homopolymer of propylene or a copolymer of propylene with ethylene or an alpha olefin;
- a polymeric compatibilizer comprising at least one styrene monoolefin copolymer and at least one styrene diolefin copolymer, wherein each copolymer is present in an amount sufficient to facilitate adhesion between the components of the polyolefin blend;
- and an ABS resin component of an acrylonitrile-butadiene-styrene resin or a blend of styrene-acrylonitrile resin with a diene, the ABS resin component being present to render the polyolefin blend suitable for electroplating,
- wherein the article has a desired form, shape, and an exterior surface, and then first depositing an initial conductive metal onto at least a portion of the surface of the article, and secondly plating the polyolefin article with a second metal.
