PROCESS FOR PHOTOCATALYTIC POLYMERIZATION OF CYCLIC OLEFINS IN PRESENCE OF RUTHENIUM OR OSMIUM CATALYST CONTAINING PHOTOLABILE LIGANDS, COMPOSITION AND COATED CARRIER Russian patent published in 1999 - IPC

FIELD: polymerization processes. SUBSTANCE: photocatalytic cycle-opening polymerization of cyclic olefin or at least two different cyclic olefins in presence of catalyst containing ruthenium or osmium compounds is distinguished by that photochemical metathetical polymerization is carried out upon irradiation within wavelength range from UV region to that close to IR region in presence of catalytic amount of at least one heat-resistant ruthenium or osmium compound containing at least one photolabile ligand bound to metal atom, remaining coordination vacancies being occupied by non-photolabile ligands. EFFECT: simplified process and increased its economical efficiency. 53 cl, 6 tbl
