A compatibilized polymeric polyblend composition comprising: (A) from about 40 to about 95 weight percent of a vinylidene chloride interpolymer, the interpolymer being formed from a monomer mixture comprising vinylidene chloride in an amount of from about 60 to about 98 weight percent, said weight percents being based on the total weight of the monomer mixture, and at least one monoethylenically unsaturated monomer copolymerizable therewith in an amount of from about 40 to about 2 weight percent, based on the total weight of the monomer mixture; (B) a polyvinyl halide formed from a monomer mixture of at least 50 weight percent of a halo-substituted ethylenically unsaturated monomer, with the balance being an ethylenically unsaturated monomer copolymerizable therewith; and (C) a compatibilizing amount of a compatibilizing polymer, said compatibilizing polymer being selected from the group consisting of (1) olefin polymers having halogen chemically affixed thereto in an amount of from about 24 to about 44 percent by weight of polymer; (2) a polymer formed from a monomer mixture having between about 65 weight percent to about 40 weight percent of vinyl aromatic monomers and between about 35 to about 60 weight percent of at least one ethylenically unsaturated mono- or polybasic carboxylic acid and derivative thereof, said weight percentages being based upon the total weight of the monomer mixtures; (3) a thermoplastic copolyester resin, said thermoplastic copolyester resin being formed from an acidic component, comprising one or more dibasic acid and a polyol component comprising more than one polyhydric alcohol, said polyhydric alcohols having a molecular weight of less than about 300; and (4) a thermoplastic graft copolymer of a rubber substrate and at least one comonomer on the substrate, the substrate having a rubber glass transition temperature below 0°C., and the monomer selected from the group consisting of C1-C8 alkyl acrylates and C1-C8 alkyl methacrylates, provided that the monomer selected is different from the major monomeric component of the rubber substrate.
