ADDITIVE FOR GAS PHASE POLYMERIZATION PROCESSES

摘要

A polymerization process including: polymerizing at least one olefin to form an olefin based polymer in a gas phase polymerization reactor; and feeding at least one polysulfone additive system to the polymerization reactor, wherein the polysulfone additive system includes a polysulfone copolymer, a polymeric polyamine, and an oil-soluble sulfonic acid.
