Patent

CA 2539560

The instant invention relates to new metathesis oligomers which are substituted with fluori~nated groups. Also disclosed is a polymerisable composition comprising a catalytically effec~tive amount of a penta- or hexavalent ruthenium or osmium carbene catalyst, the process for preparing the metathesis oligomers by applying the reaction conditions of Ring Opening Metathesis Polymerisation (ROMP) to the polymerisable composition. These new methathe~sis oligomers are useful for increasing the oil and water repellency of organic materials.

La présente invention porte sur de nouveaux oligomères obtenus par métathèse qui sont substitués par des groupes fluorés. L'invention porte également sur une composition polymérisable comprenant une quantité effective d'un point de vue catalytique d'un catalyseur de carbène d'osmium ou de ruthénium penta- ou hexavalent, sur le procédé de préparation des oligomères obtenus par métahèse qui consiste à appliquer à la composition polymérisable les conditions de la réaction de la polymérisation par métathèse avec ouverture de cycle. Ces nouveaux oligomères méthathe-sis sont utiles pour intensifier le caractère oléfuge ou hydrofuge des matériaux organiques.
