    摘要： 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.

    摘要翻译： 聚合物共混物包含至少一种乙烯/α-烯烃互聚物和至少一种聚烯烃。 聚烯烃可以是均聚物或互聚物，并且具有至少约6cN的熔体强度。 乙烯/α-烯烃互聚物是至少具有硬嵌段和至少一个软嵌段的嵌段共聚物。 软块包含比硬块更高量的共聚单体。 嵌段互聚物具有这里公开的许多独特特征。 聚合物共混物可以成型挤压成型材，垫片和其他产品。

    摘要： 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.

    摘要翻译： 通过将互聚物与至少一种支化聚烯烃共混来实现乙烯/α-烯烃互聚物的流变改性。 聚烯烃可以是均聚物或互聚物并且具有小于1的支化指数。乙烯/α-烯烃互聚物是具有至少一个硬嵌段和至少一个软嵌段的嵌段共聚物。 软块包含比硬块更高量的共聚单体。 嵌段互聚物具有这里公开的许多独特特征。 流变改性的乙烯/α-烯烃互聚物，即所得的聚合物共混物，可被挤出或模制成许多有用的制品，如薄膜，片材，型材，垫圈，泡沫等。
