Abstract
A process for preventing polymeragglomeration and for controlling the density of copolymer produced by an alpha-olefin copolymerization process in a polymerization reactor, wherein the ratio of the flow rates of introduction of the comonomer(s) to the monomer is kept constant.
Claims13
A process for preventing polymer agglomeration and for controlling the density of a copolymer produced by a continuous copolymerization process comprising copolymerizing in a continuous polymerization reaction a monomer and at least one comonomer in a polymerization reactor in the presence of a polymerization catalyst, said monomer and said at least one comonomer being alpha-olefins having from 2 to 6 carbon atoms, wherein the ratio of the flow rates of introduction into the polymerization reaction of said at least one comonomer to the monomer is kept constant.
