<p>There is disclosed a triazine-phenol-aldehyde condensate which contains at least 15% of nitrogen, has a melt viscosity of not greater than 2,000 cps at 175 DEG C and a solubility of at least 80% by weight at 25 DEG C by the 90:10 methanol: water method. Also disclosed are methods for the manufacture of the condensate as well as its use in fire-retardant epoxy resin compositions suitable fro the manufacture of laminates for electronic applications. Additionally, disclosed is a compositon comprising a physical mixture of a triazine-phenol-aldehyde condensate with benzoguanamine and/or acetoguanamine wherein the mixture contains from about 0.5% ti 20% if benzoguanamine, acetoguanamine and mixtures thereof based on the weight of the condensate. There is also disclosed a glycidylated triazine-phenol-aldehyde condensate of this invention.</p> |
