A polymeric composition is disclosed. The composition comprises a solid halide polymer, selected from vinyl halide polymers and vinylidene halide polymers, a terpolymer comprising by weight (a) 40 to 80 percent ethylene, (b) 3 to 30 percent carbon monoxide and (c) 5 to 60 percent of one or more monomers copolymerizable therewith in order to produce solid copolymers and a mixture comprising (a') a mixed alkyl phthalate and (b') a copolymer of from about 5 to about 95 percent by weight of an alkyl acrylate wherein the alkyl radical contains from 1 to 12 carbon atoms and from about 95 to about 5 percent by weight of a dissimilar alkyl acrylate wherein the alkyl radical contains from 3 to 24 carbon atoms, the alkyl phthalate being present in an amount by weight at least equal to the amount of the copolymer (b'). |
