    摘要: Cycloolefin block copolymers and a process for their preparation Cycloolefin block copolymers, which in particular are suitable as phase promoters, are preferably obtained by copolymerization of polycyclic olefins, such as norbornene, with acyclic olefins, such as ethylene, by, at a molecular weight distribution M.sub.w /M.sub.n of the polymer block forming of less than 2, changing the reaction conditions one or more times in such a way that the monomer/comonomer ratio changes by at least 10% or a further polymerizable monomer is metered into the monomer or the monomers.
