Rubbery polymer

A process for preparing a rubbery polymer having good heat and ultraviolet light resistance, said process comprising the steps of (1) polymerizing (a) butyl acrylate, (b) an alkoxyalkylene acrylate, and (c) a crosslinking agent under emulsion polymerization conditions to produce a seed polymer containing latex;

• (2) adding (a) styrene, and (b) additional crosslinking agent to the seed polymer containing latex under emulsion polymerization conditions which result in the formation of an emulsion containing the rubbery polymer;
• and (3) recovering the rubbery polymer from the emulsion containing the rubbery polymer.

A leathery composition which is useful in automotive applications which is comprised of (1) a polyolefin, (2) a plasticizer, and (3) a rubbery polymer which is comprised of repeat units which are derived from (a) butyl acrylate, (b) an alkoxyalkylene acrylate, (c) styrene, (d) a half ester maleate soap, and (e) a crosslinking agent.

A panel for automotive applications which is comprised of a semirigid urethane foam which is supported by a rigid backing, wherein said semirigid urethane foam is covered with a leathery skin which is comprised of (1) a polyolefin, (2) a plasticizer, and (3) a rubbery polymer which is comprised of repeat units which are derived from (a) butyl acrylate, (b) an alkoxyalkylene acrylate, (c) styrene, (d) a half ester maleate soap, and (e) a crosslinking agent.

A leathery composition which is useful in automotive applications wherein said composition contains from about 40 to about 160 parts by weight of a rubbery polymer which is comprised of repeat units which are derived from (a) butyl acrylate, (b) an alkoxyalkylene acrylate, (c) styrene, (d) a half ester maleate soap, and (e) a crosslinking agent, from about 10 to about 50 parts by weight of a plasticizer, and from about 0.1 to about 5 parts by weight of antidegradants.
