Abstract
The invention relates to metathesis polymers wherein an aromatic group that has UV-light absorbing properties is attached with a bridge group to the polymer. Also disclosed is a polymerizable composition comprising a catalytically effective amount of a penta- or hexavalent ruthenium or osmium carbene catalyst, the process for preparing the metathesis polymer by applying the reaction conditions of Ring Opening Metathesis Polymerization (=ROMP) to the polymerizable composition; and various technical applications of the metathesis polymers.
