Abstract: Compounds of Formula I ##STR1## wherein Z is an aromatic group, each R is individually selected from the group consisting of alkyl groups of from 1 to about 12 carbon atoms, thioalkyl groups of from 1 to about 12 carbon atoms, and halogen atoms, n is from 1 to about 6, and x is from 0 to 7, are suitable for use in preparing rubber latex particles. The rubbers are useful as substrates in graft copolymers and the resulting graft copolymers are suitable for use in thermoplastic blend compositions, particularly with transparent polymers. The rubber materials are advantageous in that they exhibit low glass transition temperatures and high refractive indices.

Abstract: An improved method for carboxylating styrenic resins and particularly impact-modified styrenic resins such as ABS resins, by melt-processing a mixture comprising the styrenic resin, an ethylenically-unsaturated carboxylic compound, and, optionally, a free-radical generator.

Abstract: A modified propylene polymer composition of improved low temperature impact resistance comprising about 55 to about 80 weight percent polypropylene homopolymer, about 15 to about 30 weight percent linear low density polyethylene and about 5 to about 15 weight percent polybutene.

Abstract: An improved method for making alloys of styrenic resins and polyamides. The styrenic resin is first melt-processed with an ethylenically-unsaturated carboxylic compound, optionally in the presence of a free-radical generator, then combined with the polyamide under melt-processing conditions. The compositions remain thermally-processable and generally exhibit good impact properties with little or no delamination.
