High temperature olefin polymerization process

Abstract From the Canadian patent

A polymerization process for olefinically or acetylenically unsaturated monomers, is disclosed. The process comprises contacting the one or more of the monomers with a, suitable ionic catalyst composition comprising the reaction product of a catalytically, suitable Group 4, 5, 6 or 8 transition metal compound having a univalent hydride, alkyl or, silyl ligand and a hydrated salt. The class of preferred anion precursors consists of, hydrated salts comprising a Group 1 or 2 canon and a non-coordinating anion. Using the, preferred ionic catalysts high temperature processes e.g. at or above , 90°C can be, conducted to prepare polyolefins particularly ethylene copolymers, of both high …
