Abstract
This invention relates to polyolefin compositions. In particular, the invention pertains to elastic polymer compositions that can be more easily processed on cast film lines, extrusion lamination or coating lines due to improved resistance to draw resonance. The compositions of the present invention comprise an elastomeric polyolefin resin and a high pressure low density type resin. The preferred compositions of the present invention comprise from 88 to 99 percent elastomer or plastomer and from 1 to 12 percent by weight of a high pressure low density type resin.
