| titleOfInvention | Linear low density polyethylene with homogeneous or inverted comonomer composition distribution |
| abstract | a) a density of 900 to 925 kg / m 3 according to ISO 1183, b) 1 to 16 wt% C 4 -C 10 comonomer content measured by Fourier transform infrared spectroscopy, c) at least 200 as determined by gel permeation chromatography 000 g / mol, weight average molecular weight, Mw, d) According to Crystallisation Analysis Fractionation (CRYSTAF), linear low density polyethylene is crystalline at temperatures below 30 ° C, up to 10 wt% of soluble amorphous fractions and from 60 ° C to 75 ° C. A crystallising polymer component having a fraction of at least 35 wt% and e) having an elution temperature range of 60 ° C. to 94 ° C. by e.g. Temperature Rising Elution Fractionation (TREF) analysis. Molecular weight distribution by a gel permeation chromatography apparatus (GPC-FTIR) combined with a Fourier transform infrared spectroscopy, and f) less than 10 wt% of a crystalline polymer component having at least 70 wt% and an elution temperature range of 30 ° C. to 60 ° C. MWD) A substantially constant short chain branching profile, or g) reverse short chain branching profile conditions across the molecular weight distribution (MWD) by gel permeation chromatography apparatus (GPC-FTIR) combined with Fourier transform infrared spectroscopy. Satisfactory Ziegler-Natta catalysis is provided for linear low density polyethylene. The linear low density polyethylene is a special Ziegler-Natta procatalyst and the formula (IV) (C 1 -C 4 -alkyl) m -Al-X 3 -m , wherein X is chlorine, bromine, iodine or fluorine 1 or 2) in the presence of a halogenated aluminum alkyl cocatalyst. |
