CA 2368403

A novel process for producing homopolymers and interpolymers of olefins which involves contacting an olefin and/or an olefin and at least one or more other olefin(s) under polymerization conditions with a metallocene catalyst and at least one ether comprising at least one carbon-oxygen-carbon linkage (C-O-C) of the formula R1-O(-R2-O)m-R3 in amounts sufficient to reduce the electrostatic charge in the polymerization medium. Also disclosed is a process for reducing electrostatic charge in an olefin polymerization medium.

L'invention concerne un nouveau procédé de production d'homopolymères et d'interpolymères d'oléfines consistant à mettre en contact une oléfine et/ou une oléfine et au moins une ou plusieurs autres oléfine(s) dans des conditions de polymérisation avec un catalyseur métallocène et au moins un éther comprenant au moins une liaison carbone-oxygène-carbone (C-O-C) de formule R?1¿-O(-R?2¿-O)¿m?-R?3¿ en quantité suffisante pour réduire la charge électrostatique dans le milieu de polymérisation. Fait aussi l'objet de cette invention un procédé de réduction de la charge électrostatique dans un milieu de polymérisation d'oléfines.
