There is a need for halogen-free polymeric compositions that offer high tensile strength and high tear strength as well as increased heat and ultraviolet light resistance. For instance, it is particularly critical for polymers that are utilized in making skin compounds for automotive instrument and door panels to offer high modulus as well as to display excellent heat and ultraviolet light resistance. This invention discloses a polymeric composition comprising (1) a compatibilizing polymer selected from the group consisting of ethylene vinyl acetate and ethylene alkyl acrylates, (2) a polyolefin, (3) a free radical generator and (4) 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.
