摘要:
The invention provides a process for reducing the low molecular weight oligomer content of olefin polymers produced by metallocene catalysis wherein at least one organometallic compound is fed continuously into the reactor during polymerization. The organometallic compound has the formula R1nA, wherein A is a Periodic Table Group 12 or 13 element. R1 is the same or different, substituted or unsubstituted, straight or branched chain alkylradical, cyclic hydrocarbyl radical, alkyl-cyclohydrocarbyl radical, aromatic radical or alkoxide radical and n is 2 or 3, to form a polymer product having a content of said compound of at least about 50 weight ppm.
