Abstract
There is a need for polymers that offer a high level of heat and ultraviolet light resistance. It is particularly critical for polymers that are utilized in making skin compounds for automotive instrument and door panels to display excellent heat and ultraviolet light resistance. Polymer blends having such characteristics can be made by blending certain rubbery polymers with halogen containing polymers, such as polyvinyl chloride (PVC). There is currently a demand for halogen-free polymers having such characteristics. This invention discloses a rubbery polymer that can be blended with polyolefins, such as polyethylene or polypropylene, to make leathery compositions having good heat and ultraviolet light resistance. The rubbery polymer of this invention is comprised of repeat units which are comprised of (a) butyl acrylate, (b) an alkoxyalkylene acrylate, (c) styrene, (d) a half ester maleate soap, and (e) a crosslinking agent.
