CHROMIUM-CONTAINING CATALYST, PROCESS FOR ITS PREPARATION WITH SULFUR TREATMENT AND USE THEREOF IN OLEFIN POLYMERIZATION

摘要

High melt flow olefin polymers suitable for such applications as injection molding, and the like requiring a narrow molecular weight distribution are produced using a catalyst made by treating a chromium catalyst on a silica-containing base with a sulfur-containing material, and thereafter reoxidizing.
