Epoxy-vinyl copolymerization type liquid resin composition, cured product of the same, electronic/electric apparatus using the cured product, and method of producing the cured product

摘要

The present invention provides an epoxy-vinyl copolymerization type liquid resin composition and a cured product of the same. The resin composition contains: an epoxy resin having an epoxy resin equivalent of not more than 200 g/eq; an acid anhydride having an unsaturated double bond that is liquid at normal temperature or the acid anhydride having an unsaturated double bond that is liquid at normal temperature and maleic anhydride; a polyfunctional monomer which is liquid at normal temperature; an epoxy resin curing catalyst which accelerates a curing reaction of the epoxy resin with the acid anhydride or with the acid anhydride and maleic anhydride; and a radical polymerization catalyst which accelerates a curing reaction of the polyfunctional monomer.

1. An epoxy-vinyl copolymerization type liquid resin composition containing:
an epoxy resin having an epoxy equivalent of not more than 200 g/eq; an acid anhydride having an unsaturated double bond that is liquid at 25° C., further containing maleic anhydride in an amount of 1 to 33 mol % based on the total amount of the acid anhydride and maleic anhydride; a polyfunctional vinyl monomer which is liquid at 25° C.; an epoxy resin curing catalyst which accelerates a curing reaction of the epoxy resin with the acid anhydride and maleic anhydride; and a radical polymerization catalyst which accelerates a curing reaction of the polyfunctional vinyl monomer, wherein the resin composition is capable of forming, through curing, a cured product which is a copolymer of the epoxy resin, the acid anhydride and maleic anhydride, and the polyfunctional vinyl monomer.
