FIELD: chemistry.
SUBSTANCE: composition for manufacturing an automobile material with a melt flow rate MFR2 (230°C) in the range from 10 to 50 g/10 min, which contains two heterophase polypropylenes, including a propylene homopolymer-based matrix and elastomer copolymer, plastomer and a mineral filling agent. Heterophase polypropylenes possess different rates of melt flow: the first heterophase polypropylene with a melt flow rate MFR2 (230°C) in the range from 3.0 to 30.0 g/10 min and the second heterophase polypropylene with weight content of substances soluble in cold xylol (XCS) in the range from 7.0 to 20.0%.
EFFECT: invention makes it possible to obtain the composition, possessing sufficient rigidity, plasticity and a high melt flow rate.
