Abstract:
A process for polymerizing an olefin and/or an olefin and at least one or more other olefin(s) comprising contacting, under polymerization conditions, in a polymerization medium wherein electrostatic charge is present, the olefin and/or the olefin and at least one or more other olefin(s) with at least one Ziegler-Natta catalyst comprised of a component comprising at least one transition metal and a co-catalyst comprising at least one organometallic compound, and at least one ether comprising at least one carbon-oxygen-carbon linkage (C--O--C ) having the formula,R.sup.1 --O(--R.sup.2 --O).sub.m --R.sup.3whereinm ranges from 0 to 30,R.sup.1, R.sup.2 and R.sup.3 independently contain from 1 to 30 carbon atoms and from 0 to 30 heteroatoms of an element, or mixtures thereof, selected from Groups 13, 14, 15, 16 and 17 of the Periodic Table of Elements as defined herein, and further wherein R.sup.1, R.sup.2 and/or R.sup.3 can be linked and form part of a cyclic or polycyclic structure, wherein the ether is present in an amount sufficient to reduce the electrostatic charge in the polymerization medium.
