Process for the continuous gas-phase (co-)polymerisation of olefins in a fluidised bed reactor

摘要

A process for the gas-phase (co-)polymerization of olefins in a fluidized bed reactor using a chromium oxide catalyst wherein the polymerization is performed in the presence of a process aid additive selected from at least one of (1) a polysulphone copolymer, (2) a polymeric polyamine, and (3) an oil-soluble sulphonic acid.
