Title:
BIFUNCTIONAL ORGANOPOLYSILOXANE, DUAL-CURABLE ORGANOPOLYSILOXANE COMPOSITION, CURED ARTICLE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009810
Kind Code:
A1
Abstract:
A novel organopolysiloxane represented by average formula (1) can be cured rapidly by the irradiation with ultraviolet ray and can be cured satisfactorily even in a shaded part which ultraviolet ray cannot reach when a dual-curable organopolysiloxane composition comprising specified amounts of the polysiloxane, a photopolymerization initiator and a condensation-curing catalyst is prepared. (R1 represents a monovalent hydrocarbon group, a group represented by formula (2) or a group represented by formula (3), in which at least one group represented by formula (2) and at least one group represented by formula (3) are contained; and m represents 1 to 10,000.) (R2 represents a group containing an acryloyl group, a methacryloyl group, an acryloyloxy group or a methacryloyloxy group; and R3 represents a bivalent hydrocarbon group.) (R4 and R each independently represent a monovalent hydrocarbon group; a represents 0 to 2; and R3 is as defined above.)
