There is a need for halogen-free polymeric compositions which offer increased heat and ultraviolet light resistance for utilization in automotive interiors. For instance, it is particularly critical for polymers which are utilized in making skin compounds for automotive instrument and door panels to display excellent heat and ultraviolet light resistance. This invention discloses a leathery composition which is useful in automotive applications which is comprised of (1) a compatibilizing polymer selected from the group consisting of ethylene vinyl acetate and ethylene alkyl acrylates, (2) a polyolefin and (3) a rubbery polymer which is comprised of repeat units which are derived from (a) butyl acrylate, or optionally a mixture of butyl acrylate and 2-ethylhexyl acrylate containing up to about 40 percent 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 and (e) a crosslinking agent.
