Cyclic organosiloxane containing imide bond and polymerizable unsaturated bond, and curable resin composition comprising said cyclic organosiloxane

Abstract

The purpose of the present invention is to provide: a cyclic organosiloxane which contains an imide bond and a polymerizable unsaturated bond, and which provides a cured product having excellent hardness and bending resistance; and a curable resin composition comprising the cyclic organosiloxane. The present invention provides: a cyclic organosiloxane which contains an imide bond and a polymerizable unsaturated bond and which is represented by general formula (1); and a curable resin composition comprising the cyclic organosiloxane. (In the formula, each R1 independently represents a monovalent hydrocarbon group or a hydrogen atom for which there may be at least one interposed atom selected from oxygen, nitrogen, sulfur, and phosphorus; each Z is independently a monovalent organic group which has an imide bond and a polymerizable unsaturated bond and for which there may be at least one interposed atom selected from oxygen, nitrogen, sulfur, and phosphorus; n is an integer of 2-6; m is an integer of 0-4; and the sum of n+m is 4-6. The arrangement of a siloxane unit in parentheses may be arbitrary.)
