Abstract: A film made from or containing a polyolefin composition made from or containing: A) from about 19 wt % to about 50 wt %, based upon the total weight of the polyolefin composition, of a propylene ethylene copolymer having an ethylene derived units content ranging from about 1.5 wt % to about 6.0 wt %, based upon the total weight of the propylene ethylene copolymer; and B) from about 50 wt % to about 81 wt %, based upon the total weight of the polyolefin composition, of a propylene ethylene 1-butene terpolymer having an ethylene derived units content ranging from about 1.5 wt % to about 6.0 wt %, based upon the total weight of the propylene ethylene 1-butene terpolymer, and 1-butene derived units content of between about 4.8 wt % and about 12.4 wt %, based upon the total weight of the propylene ethylene 1-butene terpolymer; the sum of the amount of component A) and B) being 100.

Abstract: Catalyst components component for the (co)polymerization of olefins CH2═CHR, in which R is a hydrocarbyl radical with 1-12 carbon atoms, optionally in mixture with ethylene, comprising Ti, Mg, Zn, Cl, and an electron donor compound characterized by the fact that more than 50% of the titanium atoms are in the +4 valence state, and that the amount of Zn ranges from 0.1 to 4% by weight based on then total weight of said solid catalyst component.
