摘要： An oriented multilayer film is provided, the film including in at least one outer layer an ethylene copolymer having a density of 0.900-0.935 g/cm3 and a CDBI of 50-95% the outer layer is in contact with a polypropylene core layer, and the film is made by coextrusion of the ethylene copolymer and the polypropylene layer and subsequent orientation. The coextruded layers can be uniaxially oriented or biaxially oriented without difficulties caused by presence of low molecular weight amorphous polymer fractions inherently present in traditional Ziegler-Natta linear low density polyethylene. The optical properties of oriented polypropylene films can be retained, while the sealing temperature is lowered and the heat seal strength and the hot tack performance properties are improved.
摘要翻译：提供取向多层膜，所述膜在至少一个外层中包含密度为0.900-0.935g / cm 3的乙烯共聚物和外层的50-95％的CDBI与聚丙烯芯层接触，并且该膜通过乙烯共聚物和聚丙烯层的共挤出和随后的取向制成。共挤出层可以是单轴取向的或双轴取向的，而由传统的齐格勒 - 纳塔线性低密度聚乙烯中固有存在的低分子量无定形聚合物组分的存在所困难。可以保持定向聚丙烯膜的光学性能，同时降低密封温度，提高热封强度和热粘性能。

摘要： This invention relates to blown films produced from copolymer made by a process for polymerizing olefins in which the amount of trimethylaluminum in a methylalumoxane solution is adjusted to be from 1 to 25 mol %, prior to use as an activator, where the mol % trimethylaluminum is determined by 1H NMR of the solution prior to combination with any support. This invention also relates to a process for polymerizing olefins in which the amount of an unknown species present in a methylalumoxane solution is adjusted to be from 0.10 to 0.65 integration units prior to use as an activator, where the amount of the unknown species is determined by the 1H NMR spectra of the solution performed prior to combination with any support. Preferably, the methylalumoxane solution is present in a catalyst system also comprising a metallocene transition metal compound.
