A method for the production of solid, high molecular weight, highly crystalline polyolefins

摘要

Process for polymerizing alpha-olefins employing a catalyst comprising organopolylithiumalumaluminum compound prepared by reacting lithium compounds selected from the group consisting of lithium hydride and lithium alkyl with at least one aluminum compound selected from the group consisting of aluminum trialkyl and dialkyl aluminum hydride, an alkyl compound selected from the group consisting of lithium alkyl, aluminum trialkyl and dialkyl aluminum hydride and the alpha form of TiCl3. This combination provides a catalyst for commercial processes which can be operated at temperatures above 140 DEG C. over extended periods of time.
