Abstract:
1. A polyolefin composition comprising: A) 14-18 parts by weight of a homopolymer of propylene or a copolymer of propylene with ethylene and/or one or more CH B) 5-18 parts by weight of a propylene copolymer fraction containing ethylene derived units, said fraction being insoluble in xylene at room temperature; and C) 72-80 parts by weight of a propylene copolymer fraction containing units derived from a comonomer selected from ethylene and mixtures of ethylene with one or more CH the percent by weight of the sum of the B and C fractions with respect to the total polyolefin composition being from 82% to 86%, wherein the haze of said composition is less than 25%, wherein the quantity of ethylene plus optional α-olefin in the total composition is from 15 to 22% by weight, and wherein a difference in the weight percent ethylene content of fraction B) and the weight percent ethylene content of fraction C) is not more than 1.8 weight percent.
