Polyethylene composition comprising (percentages by weight): A) from 60 to 95% of an LLDPE copolymer having a density from 0.905 to 0.9 g/cm , M /M values less than 4 and F/E ratio values greater than 20; B) from 5 to 40% of one or more crystalline copolymers of propylene selected from among defined copolymers of propylene with ethylene and/or higher alpha-olefins.

Polyethylene compositions having improved optical and mechanical properties and improved processability in the melted state

Polyethylene composition comprising (percentages by weight): A) from 60 to 95% of an LLDPE copolymer having a density from 0.905 to 0.935 g/cm , {overscore (M)} /{overscore (M)} values less than 4 and F/E ratio values from 10 to 20; B) from 5 to 40% of one or more crystalline copolymers of propylene selected among defined copolymers of propylene with ethylene and/or higher alpha-olefins.

Polyethylene compositions having improved mechanical properties and improved processability in the melted state

Polyolefin compositions containing from 70 to 99 parts by weight of a composition (A) that includes (i) from 75 to 95% by weight of a copolymer of ethylene with an &agr;-olefin CH,&boxH;CHR, where R is an alkyl radical having from 1 to 10 carbon atoms; and (ii) from 5 to 25% by weight of a copolymer of propylene with ethylene and/or an &agr;-olefin CH,&boxH;CHR,, where R,is an alkyl radical having from 2 to 10 carbon atoms, and from 1 to 30 parts by weight of a polyolefin component (B) that includes crystalline polybutene-1. The compositions can be used for making films.
