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.

Elastomeric resin compositions with improved resistance to draw resonance

Multicomponent thermoplastic resin blends are disclosed which have a nonisothermal crystallization half life of less than thirty seconds. Especially preferred are three component resin blends comprising a maleic anhydride grafted HDPE, an unmodified LLDPE copolymer having a density between about 0.905 and 0.93 g/cc, and an unmodified LLDPE copolymer having a density between about 0.89 and 0.92 g/cc. These thermoplastic resin blends can be used as the adhesive layer in multilayer structures. They are especially useful in blown film multilayer structures and they show particularly good adhesion to polar substrates, e.g., EVOH substrates.
