FIELD: chemistry.SUBSTANCE: invention relates to a thermoplastic polyolefin composition for pressure moulding painted and flame pretreated articles. The composition contains a continuous phase (matrix) (M) of a propylene homopolymer or a propylene copolymer with weight content of the comonomer of not more than 20%, which form a dispersion phase (E) with characteristic viscosity of at least 2.2 dl/g, a first elastomer which is copolymer rubber based on ethylene-C-C-alpha-olefin, and a second elastomer, and inorganic filler. The second elastomer is different from the first elastomer and is a random copolymer based on ethylene/alpha-olefins, the composition of which includes ethylene and up to 45% of one or more C-Calpha-olefins.EFFECT: articles pressure moulded from the disclosed composition have low or no sensitivity to flame treatment during flame pretreatment before depositing a clean paint layer and also demonstrate high heat conductivity.10 cl, 4 tbl, 15 ex |
