摘要:
A co-extruded laminate of at least one layer of an ionomer and at least one layer of an acid polymer that can be thermoformed with a plastic substrate such as a polyolefin. The laminate can be pigmented to eliminate the need to paint the surface of the plastic substrate. Articles can be formed from the laminated substrate such as automotive parts and sporting equipment.
摘要:
The present invention includes a laminate and formation of a laminate having at least one layer of an ionomer and at least one layer of an acid polymer or blend of acid polymer and a thermoplastic polyolefin that can be thermoformed to form a shaped laminate. The shaped laminate can then be contacted with a plastic substrate such as a thermoplastic polyolefin to form a composite article by such means as, for example, injection molding. The laminate can be pigmented to eliminate the need to paint the surface of the plastic substrate. Impact and scratch resistant articles can be formed from the laminated substrate such as automotive parts, appliance body parts and sporting equipment.

Plastic toughened plastics include a polymer composition having a polypropylene component and a second polymer component. The polypropylene component is present in an amount from about 50 to about 95 weight percent based on the total weight of the blend. The second polymer component is present in an amount from about 5 to about 50 weight percent based on the total weight of the blend, is a BOCD or BCD blend of at least two ssPE components, and has an overall density greater than about 0.90 g/cm3. Optionally, the plastic toughened plastics include one or more third polymer component selected from propylene-olefin elastomers and ethylene-propylene rubbers, which are present in an amount from about 1 to about 50 weight percent, based on the total weight of the blend.
