摘要： The present invention relates to a polypropylene composition comprising: a first polypropylene homopolymer or random copolymer (PPR1) having a comonomer content lower than the comonomer content of the second polypropylene, a second polypropylene (PPR2) which is a random copolymer of propylene and of the comonomer; said comonomer being an alpha-olefin different from propylene, the melting temperature of the polypropylene composition (Tm(PPR)) being defined as Tm(PPR) > 165 - 6.9*[total comonomer content] - 8.4*[comonomer content of the first polypropylene], the difference between the melting temperature and the crystallization temperature of the polypropylene composition ranges from 27 and 33, and a xylene soluble fraction (XS) at 23°C of not more than 1.5 wt. %. The present invention also relates to a process for the preparation of said polypropylene composition. The present invention further relates to the use of said polypropylene composition for producing films or moulded articles.
摘要翻译：本发明涉及一种聚丙烯组合物，其包含：第一聚丙烯均聚物或无规共聚物（PPR1），其共聚单体含量低于第二聚丙烯的共聚单体含量;第二聚丙烯（PPR2），其为丙烯和共聚单体; 所述共聚单体是与丙烯不同的α-烯烃，所述聚丙烯组合物的熔融温度（Tm（PPR））定义为Tm（PPR）> 165-6.9 * [总共聚单体含量] - 8.4 * [共聚单体含量聚丙烯]中，聚丙烯组合物的熔融温度和结晶温度之间的差异在27和33之间，并且在23℃下的二甲苯可溶部分（XS）不超过1.5重量％％。本发明还涉及制备所述聚丙烯组合物的方法。本发明进一步涉及所述聚丙烯组合物用于生产薄膜或模塑制品的用途。

摘要： Propylene homopolymers having a melt flow index in the range from 3.0 dg/min to 8.0 dg/min can be particularly suited for high-tenacity fibers and yarns and nonwovens. The propylene homopolymers can be produced by a process that can include polymerizing propylene in presence of a Ziegler-Natta polymerization catalyst, an aluminum alkyl, hydrogen and an optional external donor.
