ABSTRACT:
Disclosed herein is a process for the production of cycloolefin random copolymers comprising flash drying a solution of a cylcoolefin random copolymer in a hydrocarbon, said solution being obtained by copolymerization of ethylene and a specific cycloolefin in said hydocarbon in the presence of a catalyst. Further proposed herein is a process for the production of cycloolefin random copolymers by copolymerization of ethylene with a specific cycloolefin of the in a hydrocarbon in the presence of a catalyst wherein said copolymerization is carried out in a polymerization reactor where a gas phase is not substantially present.
