    摘要： The present invention is directed to an elastomer composition having at least two phases, one phase comprising a very low density polyethylene “VLDPE” component and another phase comprising a propylene polymer component wherein the propylene polymer component comprises at least one branched polypropylene and the VLDPE phase is continuous. Preferably, the VLDPE component has a melt tan delta between about 0.7 and 8 as measured by parallel plate rheometer at 0.1 radians per second, 180° C., and 10 percent strain; and the ratio of the melt tan delta of the VLDPE to the melt tan delta of the propylene component is from 0.5 to 4. The invention also provides a method of making such compositions, and to low gloss articles prepared from the same. The inventive compositions are particularly suitable for fabricating thermoformed sheeting with reduced gloss, most preferably employed as a skin in a composite interior automotive article comprising a shaped article and a negative thermoformed shaped skin or as non-carpet automotive flooring.

    摘要翻译： 本发明涉及具有至少两相的弹性体组合物，一相包含极低密度聚乙烯“VLDPE”组分，另一相包含丙烯聚合物组分，其中丙烯聚合物组分包含至少一种支化聚丙烯和VLDPE相 是连续的 优选地，VLDPE组分具有在约0.7和8之间的熔体三角洲，其通过平行板流变仪以0.1弧度/秒，180℃和10％应变测量; 并且VLDPE的熔融tanδ与丙烯组分的熔融tanδ的比率为0.5-4。本发明还提供了制备这种组合物的方法，并且使由其制备的物品低光泽。 本发明的组合物特别适用于制造具有降低的光泽度的热成型片材，最优选地用作包括成型制品和负热成型皮肤的复合内部汽车制品中的皮肤，或作为非地毯汽车地板。
