    摘要: The invention relates to a copolymer composition prepared from copolymers of propene and &agr;-olefin having 2 to 12 carbon atoms, having high molecular weight, a broad molecular weight distribution and an improved comonomer distribution. The invention relates also to a process for producing the composition and the use of the composition in pipes, fittings, profiles, films and foams. The composition is a so-called reactor mixture of copolymers of said monomers comprising a first copolymer having a higher molecular weight, an &agr;-olefin content of 3 to 10 wt. % and a melt flow rate MFR2 of 0,005 to 0,8, and a second copolymer having a lower molecular weight, thus the final composition has a comonomer content of 2 to 10 wt. %, a melt flow rate MFR2 of 0,05 to 2,5 wt. %, a melt flow ratio MFR10/MFR2 of 6 to 15, and the split of the copolymers in the composition between the higher molecular weight copolymer and the lower molecular weight copolymer is from 40/60 to 70/30.
