Abstract
Disclosed are curable compositions based on a combination of polyphenylene oxide, monomeric epoxy resin, a compatibilizing metal salt of tin, and suitable curing agents. The monomeric epoxy resin comprises a polyepoxide composition comprising at least one bisphenol polyglycidyl ether having an average of at most one aliphatic hydroxy group per molecule. The composition may be used in the preparation of laminates useful as printed circuit boards.
