| abstract | Heterophasic polyolefin compositions comprising (% by weight):n n n (A) 50 to 80%, with polydispersity readings of 5.2 to 10, of isotactic pentad (mmmm) measured in fractions insoluble in xylene at 25 ° C. by 13 C-NMR. Crystalline propylene polymers; The polymer comprises at least 95% of repeating units derived from propylene;n n n (B) one or more C 3 -C 8 5-20% of the first elastomeric copolymer of α-olefin and ethylene, the copolymer comprising less than 25-40% ethylene, which is greater than 85-95% by weight soluble in xylene at room temperature and is xylene soluble The intrinsic viscosity [η] of the fractions ranges from 2.5 to 4.5 dL / g; Andn n n (C) 10 to 40% of a second elastomeric copolymer of at least one C 3 -C 8 α-olefin and ethylene; The copolymer comprises 50 to 75% ethylene, 50 to 85% by weight soluble in xylene at room temperature, and the intrinsic viscosity [η] of the xylene soluble fraction in the range of 1.8 to 4.0 dL / g.n n n Wherein the sum of the amounts of copolymer (B) and copolymer (C) ranges from 20 to 50% relative to the total amount of components (A) to (C) and the total amount of ethylene relative to the total amount of components (A) to (C) Is up to 23% by weight, the content of fractional ethylene (C 2 xif) insoluble in xylene at room temperature multiplied by the weight percent (% XIF) of the fraction insoluble in xylene at room temperature, and soluble in xylene at room temperature. The ratio between the fractional ethylene content (C 2 xsf) soluble in xylene at room temperature multiplied by the weight percent (% SXF) of the fraction, ie, (C 2 xif x% XIF) / (C 2 xsf x% SXF) is given by Satisfies the relation (I) of:n n n n n n n n [Wherein x is the total amount of ethylene]. |
