Abstract: Rigid thermoplastic articles are disclosed which have reduced surface gloss. The reduced gloss is achieved by the use of a mixture of polymers having different viscoelastic properties. The preferred embodiment is a mixture of PVC and crosslinked PVC.

Abstract: Optically transparent frosted polymeric articles are disclosed which can be produced in smooth molds. Polymeric articles, such as PVC bottles, are molded from a composition having two polymers with different viscoelastic properties. A particularly desirable composition is one containing both PVC and crosslinked PVC.

Abstract: A process for preparing a particulate vinyl polymer resin and vinyl polymer resin derived therefrom wherein, comprising polymerization in the presence of a dispersant or graft dispersant having no ionic side groups, optionally containing terminal functional groups, said dispersant is derived from repeating units of .alpha.,.beta.-unsaturated ester(s) of acrylic and/or methacrylic acid and having a molecular weight average of from about 500 to about 50,000.

Abstract: Thermoplastic elastomer resins are described which comprise vinyl halide grafted to crosslinked acrylic latex particles comprising predominantly acrylate-containing, crosslinked polymer chains derived from(A) at least one acrylate monomer of the formulaCH.sub.2 .dbd.C(R.sub.1)C(O)OR.sub.2 (I)wherein R.sub.1 is hydrogen or methyl; and R.sub.2 is an alkyl group containing from 1 to 29 carbon atoms, an alkoxy alkyl or alkyl thioalkyl group containing from 2 to about 7 carbon atoms, or a cyano alkyl group containing from 2 to about 7 carbon atoms; and(B) at least one alpha, beta-unsaturated dicarboxylic acid, provided that the dicarboxylic acid repeating units are optional when the TPE resin contains less than about 35% by weight of vinyl halide.

Abstract: Liquid vinylidene (CH.sub.2 .dbd.C<) terminated polymers are prepared by the reaction of a (1) liquid polymer having a terminal functional group selected from the group consisting of carboxyl, hydroxyl, mercaptan, amine and epoxy and (2) a compound containing both an epoxy group ##STR1## and a vinylidene group. The reaction can be catalyzed using a base. The polymers cure readily to solid elastomers which are useful as sealants, caulks, potting compounds, coatings and the like.
