    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 a random 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 α-methyl styrene plus styrene in the tetrapolymer (b) is 38 - 70 parts by weight.

    Abstract: Graft polymers are prepared by the polymerization of at least 60% by weight of indene with no more than 40% by weight of a chlorinated rubber copolymer of from 95 to 99% by weight isobutylene and from 1 to 5% by weight of isoprene. The graft polymers so obtained are thermoplastic and have unexpectedly high heat-distortion temperatures and excellent impact resistance.
