    • A polypropylene impact copolymer is disclosed. The propylene impact copolymer composition comprises from 60 to 90 percent by weight of the impact copolymer composition of a matrix phase, which can be a homopolymer polypropylene or random polypropylene copolymer having from 0.1 to 7 mol percent of units derived from ethylene or C4-C10 alpha olefins. The propylene impact copolymer composition also comprises from 10 to 40 percent by weight of the impact copolymer composition of a dispersed phase, which comprises a propylene/alpha-olefin copolymer having from 6 to 40 mol percent of units derived from ethylene or C4-C10 alpha olefins, wherein the dispersed phase has a comonomer content which is greater than the comonomer content in the matrix phase. The propylene impact copolymer composition is further characterized by having the ratio of the matrix MFR to the dispersed phase MFR being 1.2 or less. The polypropylene impact copolymers of the present invention are well suited for making spunbond fibers which can be used to make nonwoven fabrics having good haptics.
    • 公开了一种聚丙烯抗冲共聚物。 丙烯抗冲共聚物组合物包含基质相的冲击共聚物组合物的60至90重量%,其可以是具有0.1至7摩尔%的衍生自乙烯或C 4 -C 10α-烯烃的单元的均聚物聚丙烯或无规聚丙烯共聚物 烯烃。 丙烯冲击共聚物组合物还包含10至40重量%的分散相的抗冲共聚物组合物,其包含具有6至40摩尔%的衍生自乙烯或C 4 -C 10α-烯烃的单元的丙烯/α-烯烃共聚物 烯烃,其中分散相的共聚单体含量大于基体相中的共聚单体含量。 丙烯抗冲共聚物组合物的特征还在于基质MFR与分散相MFR的比例为1.2以下。 本发明的聚丙烯抗冲共聚物非常适合制造可用于制造具有良好触觉性的非织造织物的纺粘纤维。
