The invention provides a halogen-free and thermal resistant composition, including a mixture of bismaleimide and maleimide with molar ratio of 99:1-50:50; a barbituric acid, wherein the molar ratio of the mixture and the barbituric acid is 93:7-80:20; and an epoxy resin, wherein (the mixture with the barbituric acid) and the epoxy resin have a weight ratio of 5:95 to 50:50. The mixture undergoes reaction at 110-130° C. for about 2˜7 hours to form a maleimide modified epoxy resin. The procedure of forming the composition is solvent-free, thereby providing improved integrity for electronic packaging, lower curing temperature, and a simplified process.

摘要:
A high-solubility and high-adhesion poly(amide-imide-ester) resin prepared from a monomer composition comprising: (a) a diisocyanate such as diphenylmethane 4,4'diisocyanate; (b) a trimellitic anhydride; and (c) a bis-anhydride of trimellitic anhydride such as 1,2 bis(trimellitate)ethane dianhydride, dissolved in an appropriate solvent system. Each of the trimellitic anhydride and the bisanhydride of trimellitic anhydride constitutes 1 to 40%, on a molar basis, of the monomer composition and the amount of the diisocyanate is about 1.0 to 1.2 times, also on a molar basis, the sum of the trimellitic anhydride and the bis-anhydride of trimellitic anhydride. In an alternate embodiment, a fourth component (d) diacid such as isophthalic acid can be added to the monomer composition. After the polymerization reaction, the poly(amide-imide-ester) resin so produced can be diluted with a variety of organic solvents, such as xylene and dimethylacetamide, etc., and directly coated onto a copper foil to make polymer/metal laminates without going through an intermediate step involving polyamic acid.
