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.
本发明提供了形成凝聚物和树脂组合物的方法和组成物。在一种实施例中,通过反应混合物形成凝聚物,该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。凝聚物含有高达28重量%的氮,并且在175℃下的熔融粘度不超过3,000 cps。凝聚物可以在有机溶剂中溶解至少80重量%的固体物质,并保持稳定120小时或更长时间。本发明还公开了制造凝聚物的方法,以及凝聚物在适用于电子应用的阻燃环氧树脂组合物的制造中的使用。本发明还公开了一种三嗪-芳基羟基-醛凝聚物的环氧基化产物。
