FIELD: polymers. SUBSTANCE: invention relates to polyolefin composite comprising propylene-base polymeric material and partially cross-linked thermoplastic composition of olefin elastomers designated for embossed sheet making. Polyolefin composite comprises by weight from 40 to 70% of propylene-base polymeric material and 60-30% of partially cross-linked thermoplastic composition of olefin elastomers comprising of 20-80 weight p. p. of thermoplastic elastomer and 80-20 weight p. p. of rubber of triple copolymer of ethylene, propylene and diene mainly. Embossed sheet comprising polyolefin composite exhibits the improved retention of granularity. These sheets can be used for making large articles, for example, car door and instrument panels. EFFECT: valuable properties of composite and sheets. 5 cl, 1 tbl, 1 ex |
