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 preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin.
