摘要:
Methods for reinforcing chromium catalysts by the deposition of additional silica are disclosed herein. The resultant silica-reinforced chromium supported catalysts can be used to polymerize olefins to produce, for example, ethylene based homopolymers and copolymers with higher molecular weights and additional long chain branching.
