VINYL BENZYL ETHER RESIN, METHOD OF PRODUCING THAT VINYL BENZYL ETHER RESIN, CURABLE RESIN COMPOSITION, CURED PRODUCT OF THAT CURABLE RESIN COMPOSITION, AND SHIELD MEMBER

摘要

To provide a vinyl benzyl ether resin useful as a component of a curable resin composition capable of forming a cured product which has excellent dielectric characteristics (dielectric constant, dielectric loss tangent) and excellent mechanical characteristics (flexibility) and is further excellent in heat resistance (pyrolysis resistance).SOLUTION: There is provided a vinylbenzylated phenolic resin which has a skeletal structure comprising a structural site based on a difunctional phenol, a structural site having an ester linkage, and a structural site based on an alkylene diol, and has vinylbenzyl groups at both ends. Also provided is a curable resin composition which contains the resin and a radical polymerization initiator.SELECTED DRAWING: Figure 1
