ABSTRACT:
The invention relates to metathesis oligomers wherein one or more alkoxy ether groups are attached to the oligomer moiety. 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 polymerisable composition; and various technical applications of the metathesis oligomers as antifog agents.
