Abstract
The invention relates to a polyolefin copolymer composition produced with a catalyst having a metallocene, complex in a single reactor for the polymer of an &agr;-olefin monomer with one or more olefin comonomers, and a molecule weight maximum which occurs in that 50 percent by weight of the composition which has the highest weight percent comonomer content. Preferably, the composition has a comonomer partitioning fact C which is equal to or greater than 1.10 or molecule weight partitioning fact M which is equal to or greater than 1.15. Preferred composition also have at least 0.01 long chain branches per 1000 carbon atoms along the polymer backbone. These compositions with reverse molecular engineering have. superior properties and are easily processable due to the simultaneous presence of the association of high molecular weight with high comonomer content and of long chain branching.
