ABSTRACT:
A resin composition for a laminate comprises 100 parts by weight of a polyfunctional epoxy resin (I) obtained by (i)(1) glycidylizing a polycomposite formed from a blend of brominated bisphenol A and bisphenol A, or brominated bisphenol A and formaldehyde; or (2) a mixture of a polyfunctional epoxy resin and a bisphenol A-advanced epoxy resin reacted with brominated bisphenol A in a hydroxyl:epoxy equivalent ratio of from 0.05-0.5:1 and (ii) a bisphenol A-formaldehyde phenolic resin having a weight average molecular weight of from 1,000-10,000 in a hydroxyl:epoxy equivalent ratio with respect to epoxy resin (i) of from 0.7-1.2:1; and (II) from 1-60 parts by weight of a straight chain polymer (c) such as a poly(ether)sulfone, aromatic polyester, phenoxy resin, polyparabanic acid, polyetherimide or polyphenylene sulfide.
