Compositions and methods for forming condensates and resin compositions are provided. In one embodiment, a condensate is formed from a reaction mixture including a triazine monomer, an arylhydroxy monomer, an aldehyde monomer and an acid catalyst having a pKa value of greater than 3.8. The condensates contain up to 28 wt. % of nitrogen and have a melt viscosity of 3,000 cps or less at 175° C. The condensates may have a solubility of at least 80 wt. % solids dissolved in an organic solvent for 120 hours or greater. Also disclosed are methods for the manufacture of the condensate as well as the condensate's use in fire-retardant epoxy resin compositions suitable for the manufacture of laminates for electronic applications. There is also disclosed a glycidylated triazine-arylhydroxy-aldehyde condensate of this invention.
本发明提供了形成冷凝物和树脂组合物的组合物和方法。在一种实施例中,从反应混合物中形成冷凝物,该反应混合物包括三嗪单体,芳基羟基单体,醛单体和具有大于3.8的pKa值的酸催化剂。冷凝物含有高达28重量%的氮,并且在175℃下的熔融粘度为3000 cps或更低。冷凝物可以在有机溶剂中溶解至少80重量%的固体物质,并且可以在120小时或更长时间内保持。还揭示了制造冷凝物的方法以及冷凝物在适用于制造电子应用层压板的阻燃环氧树脂组成物中的使用。还揭示了本发明的环氧基三嗪-芳基羟基-醛冷凝物。
