Abstract

La présente invention concerne un procédé de polymérisation d'une oléfine à polymérisation cationique telle qu'un mélange d'isoprène et d'isobutylène, afin de produire du butyle. Le procédé est conduit sous pression réduite en présence d'un système conventionnel de catalyseur de polymérisation cationique. Un catalyseur de polymérisation cationique préféré comprend Cp*TiMe¿3? et B(C¿6?H¿5?)¿3?. En conduisant le procédé de cette manière, sous pression réduite, on peut obtenir, à température plus élevée, comparativement aux moyens habituels, un polymère avec des caractéristiques de poids moléculaire recherchées, ce qui permet d'abaisser les coûts de production et en capital de l'installation de production de ce polymère.
