In one embodiment, a con› densate 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 conden› sates may have a solubility of at least 80 wt.  % solids dis› solved 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.
