Title:
PHENOLIC RESIN MIXTURE, EPOXY RESIN MIXTURE, EPOXY RESIN COMPOSITION, AND CURED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2010/052877
Kind Code:
A1
Abstract:
Disclosed is a phenolic resin mixture which is produced by subjecting a reaction product containing a by-product produced by the halomethylation of a biphenyl to the methylene cross-linking reaction with phenol.  Also disclosed is an epoxy resin mixture produced by epoxidizing the phenolic resin mixture.  Further disclosed is an epoxy resin composition containing the epoxy resin mixture.  A cured product of the epoxy resin mixture or the epoxy resin composition containing the epoxy resin mixture has excellent flame retardancy, and has a storage modulus that is lower than those of conventional flame-retardant cured epoxy resin products by a value falling within a specific range at 250°C.  Therefore, the epoxy resin mixture or the epoxy resin composition containing the epoxy resin mixture is useful as a semiconductor sealing material that is required to have high flame retardancy and excellent lead-free solder resistance.
