    Abstract: A composition comprising an intimate admixture of (a) 50 to 98 parts by weight of chlorinated poly (vinyl chloride) and (b) 50 to 2 parts by weight of an addition tetrapolymer containing the following monomers combined in the polymer structure in the following weight percentages: where (a) plus (b) total 100 parts by weight, and the total parts by weight of combined indene plus alpha -methyl styrene plus styrene in the tetrapolymer (b) is 38-70 parts by weight.

    Abstract: A composition comprising an intimate admixture of (a) 50 to 98 parts by weight of a vinyl chloride polymer having an inherent viscosity of at least 0.4, and (b) 50 to 2 parts by weight of an addition terpolymer containing acrylonitrile, indene and a third monomer selected from methyl methacrylate or at least one monomer of the group alpha -methylstyrene and vinyl aromatics of the formula: where each R is independently selected from Cl, H and a C1 to C9 alkyl group and x = 1 or 2, combined in the polymer structure such that (1) when the third monomer is methyl methacrylate, the polymer contains in weight percents 2-35 acrylonitrile, 10-67 indene, 5-85 methyl methacrylate, and the moles of acrylonitrile plus methyl methacrylate are equal to or more than the moles of indene. (2) when the third monomer is one of both of alpha -methylstyrene and said vinyl aromatics, the polymer contains in weight percent 10-40 acrylonitrile, 5-67 indene and 4-70 of said third monomer, and the moles of acrylonitrile plus said vinyl aromatics is equal to or greater than the moles of alpha -methylstyrene plus indene.
