Abstract:
A polymerization process comprisinga) polymerizing a monomer and a comonomer in a polymerization zone, the comonomer being an approximately pure alpha-olefin;b) separating, the polymerization effluent from said polymerization zone into two fractions: a heavy fraction that contains at least one polymer, and a light fraction that comprises monomer that has not reacted, comonomer that has not reacted, as well as isomers of said comonomer;c) subjecting at least a portion of said light fraction to ethenolysis in the presence of added ethylene;d) subjecting the ethenolysis effluent to at least two separations to isolate the comonomer therefrom; ande) recycling the comonomer isolated from said ethenolysis effluent to said polymerization zone.
