    摘要: A curable method useful for encapsulating solid state devices includes (A) an epoxy resin; (B) an effective amount of a cure catalyst comprising (B1) a first latent cationic cure catalyst comprising a diaryl iodonium hexafluoroantimonate salt; (B2) a second latent cationic cure catalyst comprising (B2a) a diaryl iodonium cation, and (B2b) an anion selected from perchlorate, imidodisulfurylfluoride anion, unsubstituted and substituted (C1-C12)-hydrocarbylsulfonates, (C2-C12)-perfluoroalkanoates, tetrafluoroborate, unsubstituted and substituted tetra-(C1-C12)-hydrocarbylborates, hexafluorophosphate, hexafluoroarsenate, tris(trifluoromethylsulfonyl)methyl anion, bis(trifluoromethylsulfonyl)methyl anion, bis(trifluoromethylsulfuryl)imide anion, and combinations thereof; and (B3) a cure co-catalyst selected from free-radical generating aromatic compounds, peroxy compounds, copper (II) salts of aliphatic carboxylic acids, copper (II) salts of aromatic carboxylic acids, copper (II) acetylacetonate, and combinations thereof; and (C) about 70 to about 95 weight percent of an inorganic filler, based on the total weight of the curable composition. The composition's cure catalyst allows the use of increased filler loadings, which in turn reduces moisture absorption and thermal expansion of the cured composition.

    摘要: A curable composition includes a functionalized poly(arylene ether), an olefinically unsaturated monomer, about 0.2 to about 5 parts by weight of a curing initiator per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer, and about 0.005 to about 1 part by weight of a curing inhibitor per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer. The weight ratio of the curing initiator to the curing inhibitor is about 1.2:1 to about 50:1. The composition provides improved and reproducible flow during the early stages of molding without compromising curing time. The composition is useful for preparing plastic-packaged electronic devices.
