Abstract:

Polymer blends comprise at least an ethylene/α-olefin interpolymers and at least one polyolefin. The polyolefins can be homopolymers or interpolymers and have a melt strength of at least about 6 cN. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. The polymer blends can be profiled extruded to make profiles, gaskets, and other products.

Abstract:

Rheology modification of an ethylene/α-olefin interpolymer is achieved by blending the interpolymer with at least one branched polyolefin. The polyolefins can be homopolymers or interpolymers and have a branching index of less than 1. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Rheology-modified ethylene/α-olefin interpolymer, i. e. , the resulting polymer blends, can be extruded or molded into many useful articles, such as films, sheets, profiles, gaskets, foams, etc.
