    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.

    摘要: This invention relates to a process for polymerizing olefins in which the amount of trimethylaluminum in a methylalumoxane solution is adjusted to be from 6 to 25 mole %, prior to use as an activator, where the mole % 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 unknown species is the peak is identified in 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.

    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.
