Abstract
The present invention relates to a cycloolefin polymer having a solution viscosity <0.25 dl/g, comprising polymerized units of at least one cycloolefin and, if desired, polymerized units of one or more acyclic olefins, wherein the cycloolefin polymer has at one or both ends an olefinically unsaturated group having at least 3 carbon atoms.
