There is a need for polymers which offer increased heat resistance, ultraviolet light resistance, and low fogging characteristics for utilization in automotive interiors. It is particularly critical for polymers which are utilized in making skin compounds for automotive instrument and door panels to display excellent heat resistance, ultraviolet light resistance, and low fogging characteristics. This invention more specifically discloses a rubbery polymer which can be blended with polyvinyl chloride to make leathery compositions having good heat and ultraviolet light resistance, said rubbery polymer being comprised of repeat units which are comprised of (a) butyl acrylate, or optionally a mixture of butyl acrylate and 2-ethylhexyl acrylate containing up to about 40% 2-ethylhexyl acrylate, (b) at least one member selected from the group consisting of methyl methacrylate, ethyl methacrylate, methyl acrylate, and ethyl acrylate, (c) acrylonitrile, (d) styrene, (e) a surfactant selected from the group consisting of sulfonates and sulfate derivatives, (f) a dispersant selected from the group consisting of aromatic formaldehyde condensation products and polycarboxylates, and (g) a crosslinking agent.
