FIELD: chemistry of polymers. SUBSTANCE: new composition comprises polypropylene and neolefin thermoplastic. Polypropylene is elastomeric polyethylene having stereoregular distribution of units in chain structure, ratios of components being as follows, wt %: elastomeric polypropylene, 5-80; neolefin thermoplastics, 20-95; compatibility agents, 0-10 and, if desired, standard fillers or strengthening agents. EFFECT: final products having low rigidity, low E-modulus, and readily flowing melts having low viscosity. 11 cl, 13 ex, 1 tbl
