Title:
VINYL GROUP-CONTAINING PREPOLYMER AND CURABLE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/243262
Kind Code:
A1
Abstract:
The present invention provides a vinyl group-containing prepolymer which has excellent dielectric characteristics. A vinyl group-containing prepolymer according to one embodiment of the present invention comprises: a first moiety that is derived from a hydrogenated product of a conjugated diene polymer polyol; a second moiety that is derived from at least one of an aliphatic polyisocyanate and an alicyclic polyisocyanate; and a third moiety that is derived from a hydroxy group-containing aromatic vinyl compound. The first moiety and the second moiety are bonded to each other via a urethane bond that is formed by a reaction between a hydroxy group of the hydrogenated product and an isocyanate group of the polyisocyanate. The second moiety and the third moiety are bonded to each other via a urethane bond that is formed by a reaction between an isocyanate group of the polyisocyanate and a hydroxy group of the hydroxy group-containing aromatic vinyl compound.
