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.

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.

Frosted polymeric articles and process for producing same

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.

Rigid thermoplastic compositions capable of forming articles with matte

Liquid vinylidene (CH.sub.2 .dbd.C&lt;) 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.
