Title:
POLYFUNCTIONAL VINYL RESIN AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/241255
Kind Code:
A1
Abstract:
Provided is a resin material that exhibits high thermal conductivity while having low relative permittivity and low dielectric loss tangent, and also has high heat resistance. A polyfunctional vinyl resin represented by general formula (1). R1 independently represent a C1-8 hydrocarbon group, and R2 independently represent a hydrogen atom or a dicyclopentenyl group, at least one of the latter being a dicyclopentenyl group. X independently represent a hydrogen atom or a vinyl-group-containing aromatic group represented by formula (1a), at least one X being a vinyl-group-containing aromatic group. n represents the number of repetitions, the average of which is a number ranging from 1 to 5. Ar represents an aromatic ring.
