POLYMERIC COMPOSITE AND FORMED ARTICLE

摘要

FIELD: polymers. SUBSTANCE: invention relates to thermoplastic olefin composites used for making formed articles exhibiting the improved surface luster and solid surface. Composite comprises (1) from about 10 to about 90 mas. p. p. of propylene homopolymer, copolymer or terpolymer; (2) from about 90 to about 10 mas. p. p. of olefin polymeric composite obtained by successive polymerization for two or more stages in the presence of titanium-containing Ziegler-Natt's catalyst; (3) from about 0.1 to 10 mas. p. p. of lubricant comprising polysiloxane and saturated acid amide per 100 parts of (1) + (2). Articles made of the composite show the improved surface solidity under conditions of accelerated aging. EFFECT: improved and valuable properties of composite and articles. 9 cl, 2 tbl, 13 ex
