Polyolefin compositions having good transparancy and impact resistance even at low temperatures comprising (by weight): A) from 25 to 95 parts of a crystalline random copolymer of propylene with ethylene and/or another alpha -olefin, containing more than 85% by weight of propylene, and having Haze values lower than 25%; and B) from 5 to 75 parts of a component comprising (a) an elastomeric copolymer of ethylene with propylene and/or another alpha -olefin, and optionally with minor proportions of a diene, containing 20-80 parts of ethylene, and (b) one or more of the polymers selected from LLDPE, LDPE, 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 of (A) and calculated average density of (B) is from 0.980 to 1.015. i |
