The invention relates to linear low density polyethylene having a density in the range from about 900 kg/mto less than about 940 kg/mas determined using IS01872-2, having a molecular weight distribution (M/M) in the range from 2.5 to 3.5, having an area under the peak in the temperature range from 20 to 40&#xb0; C. determined using an analytical temperature rising elution fractionation analysis using 1,2-dichlorobenzene and a heating rate of 1&#xb0; C./min, wherein the area is in the range from 5 to 20% of the sum of the areas under all peaks determined with the analytical temperature rising elution fractionation analysis.

Catalyst composition and method for preparing the same

The present invention relates to a catalyst composition for the polymerisation of olefins comprising a support containing a single site catalyst component, a catalyst activator and a modifier wherein the modifier is the product of reacting an aluminum compound of general formula AI(R1, R2, R3) with an amine compound of general formula N(R4, R5, R6). The catalyst composition reduces fouling and/or sheeting when used to catalyse the polymerisation of olefins. The present invention also relates to a method for the polymerisation of olefins using the catalyst composition of the invention.
