A polymerization process may include: polymerizing a monomer having 4 or less carbons and a comonomer having 6 or more carbons in the presence of an inert isomer/saturate of the comonomer to yield a product stream comprising a polymer, unreacted monomer, unreacted comonomer, and the inert isomer/saturate of the comonomer; separating the product stream into (a) a polymer stream and (b) an unreacted components stream; and separating the unreacted components stream in a distillation column into (a) an overhead stream comprising the unreacted monomer and (b) a bottoms stream comprising the comonomer and the inert isomer/saturate of the comonomer, wherein a concentration of C5&#x2212; hydrocarbons in the overhead stream is higher than a concentration of the C5&#x2212; hydrocarbons in the unreacted components stream, and wherein a concentration of C6+ hydrocarbons in the bottoms stream is higher than a concentration of the C6+ hydrocarbons in the unreacted components stream.
