CARBOCATIONIC CATALYST AND PROCESS FOR USING SAID CATALYST

摘要

This invention provides for a catalyst system for the polymerization of olefin monomers to produce narrow molecular distribution polyolefins. In particular this invention provides a catalyst system comprising Lewis acid, residual water, and optionally a secondary or tertiary amine to produce narrow MWD polyolefins preferably polyisobutylene having an MWD of less than 2.5. Methods for using this catalyst system are also provided.
