METHOD FOR GAS-PHASE POLYMERIZATION OF ALPHA-OLEFIN

摘要

PURPOSE: A gas-phase polymerization method is provided to efficiently remove polymerization reaction heat, and to increase the productivity of a polymer and a catalyst. CONSTITUTION: A gas-phase polymerization method comprises the steps of: supplying cycling gas including at least one kind of alpha-olefin and inert gas to a reactor(100); polymerizing the alpha-olefin with polyolefin in a two polymerization regions divided in a reactor; and discharging the polyolefin polymer from the reactor.
