Claims
- 1. A polyolefin composition comprising (by weight):
- A) from 25 to 60 parts of a crystalline random copolymer of propylene with ethylene and/or an .alpha.-olefin of formula CH.sub.2 =CHR, wherein R is a C.sub.2 -C.sub.8 alkyl radical, said copolymer containing more than 85% by weight of propylene, and having a haze value lower than 25%;
- B) from 40 to 75 parts of a component comprising (a) an elastomeric copolymer of ethylene with propylene and/or .alpha.-olefin of formula CH.sub.2 =CHR, wherein R is a C.sub.2 -C.sub.8 alkyl radical, and optionally with minor proportions of a diene, containing 30-70 parts of ethylene, and (b) one or more of the polymers selected from the group consisting of LLDPE, LDPE and HDPE having a Melt Index higher than 0.5 g/10 min., said (a) and (b) being present in such proportions that the ratio between the density d.sub.A of (A) and the calculated average density d.sub.B of (B) is comprised from 0.980 to 1.015, and said elastomeric copolymer (a) being present in an amount of 10-20 parts with respect to the total composition, said polyolefin composition having a haze value of less than 30%, as measured according to ASTM-D 1003 on a 1 mm thick sample.
- 2. The polyolefin composition of claim 1, where component (A) is selected from a propylene-ethylene random copolymer containing from 1% to 3% by weight of ethylene, and a propylene-1-butene random copolymer containing from 1% to 4% of 1-butene.
