Polyolefin composition for manufacture of film having cling properties

Claim 1

A polyolefin composition capable of being used for the manufacture of film having cling properties, said composition consisting essentially of (A) an intimate mixture of about 75-98 weight percent of a first component and about 2-25 weight percent of a second component, wherein the first component is a polyethylene blend comprising from about 10 to about 20 weight percent of at least one homopolymer of ethylene having a density in the range of from about 0.915 to about 0.930 g/cm 3 and melt index in the range of from about 0.2 to about 10 with from 80 to about 90 weight percent of at least one copolymer of ethylene and a C 4 -C 8 α-olefin having a density in the range of from about 0.915 to about 0.930 g/cm 3 and melt index in the range of from 0.2 to about 5.0, and wherein the second component is an elastomer selected from the group consisting of a copolymer of ethylene and propylene having a Mooney viscosity in the range of from about 15 to about 70 and a copolymer comprised of ethylene, propylene and a non-conjugated diene having a Mooney viscosity in the range of from about 15 to about 70, and (B) at least about 200 parts per million, based on the weight of (A), of an agent selected from the class consisting of (a) N,N-bis(2 hydroxyethyl) alkylamine, where the alkyl group is a C 12 -C 18 alkyl group; (b) one of (i) a liquid of waxy solid organic compound selected from the group consisting of N-(3 alkoxy-2 hydroxypropyl) ethanolamine, where the alkyl of the alkoxy group is a C 10 -C 18 alkyl group, polyethylene glycol and glycerol oleate; (ii) mineral oil; (iii) a liquid polyolefin; (iv) an organic phosphate ester that is a liquid or waxy solid; and (c) mixtures of agent (a) with agent (b).
