polymer materials. SUBSTANCE: invention, in particular, relates to composition for manufacturing shoe bottom pieces or for molding sole on the top of bent stock. Composition contains, weight parts: base 100, high-styrene polymer 0.1-40.0, calcium carbonate (filler) 0.1-40.0, lube oil 5.0-40.0, colorant 0.5-1.0, antioxidant 0.5-1.0, pore agent 0.1-1.0, polymeric modifier 1.0-15.0. Base of composition is selected from: oil-filled block copolymer, mixture thereof with oil-non-filled block copolymer and lube oil, and mixture of oil- non-filled block copolymer and lube oil at 2:1 ratio. Polymeric modifier is an ethylene/vinyl acetate copolymer with 15- 30% of the latter. EFFECT: enlarged choice of polymer compositions and improved quality of sole. 5 cl, 1 tbl, 3 ex |
