    • Propylene polymers containing a matrix of a propylene homopolymer and a copolymer of propylene and other alkenes, wherein, during the separation of the propylene polymers according to tacticity and comonomer distribution of the polymer chains, by first dissolving the propylene polymers in boiling xylene, then cooling the solution at a cooling rate of 10° C./h to 25° C. and thereafter, increasing the temperature, separating the propylene polymers into fractions of different solubility, either one or more of the conditions that i) more than 20% by weight of the matrix remain undissolved on further heating to 112° C. or ii) more than 8% by weight of the matrix remain undissolved on further heating to 117° C. or iii) more than 1% by weight of the matrix remain undissolved on further heating to 122° C. are fulfilled by the matrix which remains undissolved on heating the cooled propylene polymer solution to 80° C., a process for the preparation of the propylene polymers, their use for the production of films, fibers or moldings and the films, fibers or moldings comprising these propylene polymers, are described.
    • 含有丙烯均聚物基质和丙烯与其它烯烃共聚物的丙烯聚合物,其中在根据聚合物链的立构规整度和共聚单体分布分离丙烯聚合物期间,首先将丙烯聚合物溶解在沸腾的二甲苯中,然后冷却 该溶液以10℃/ h至25℃的冷却速率,然后升高温度,将丙烯聚合物分离成不同溶解度的分数,其中的一种或多种条件为:超过20重量% 的基质在进一步加热至112°C时仍未溶解。或)在基于进一步加热至117℃时,基质重量不得超过8%。或者,更多加热时,大于1重量%的基质仍然不溶解 至122℃,通过在将冷却的丙烯聚合物溶液加热至80℃时仍未溶解的基质来实现,制备丙烯聚合物的方法,其用于p 描述了膜,纤维或模制品的引导以及包含这些丙烯聚合物的膜,纤维或模制品。
