Abstract
FIELD: chemistry. ^ SUBSTANCE: composition contains 1) 10-60 wt % propylene and hexene-1 copolymer, where said copolymer contains 0.2-10 wt % repeating units obtained from hexene-1, 2) 10-85 wt % propylene polymer selected from a propylene homopolymer and a propylene polymer with 0.1-10 wt % -olefin selected from ethylene, C4-C10--olefin, except hexene-1, and mixture thereof, and 3) 5-30 wt % copolymer of ethylene and C3-C10--olefin and optionally a diene, having ethylene content from 15 to 60 wt %. The propylene polymer is insoluble in xylene at room temperature in amount higher than 85% and has polydispersity index from 3 to 20. The disclosed polyolefin composition has modulus of elasticity in flexure higher than 1200 MPa, Izod impact strength at 20C from 5 to 20 kJ/m2 and burst pressure resistance higher than 3000 hours. ^ EFFECT: pipeline systems made from said composition have optimum balance of mechanical properties. ^ 6 cl, 1 tbl
