Abstract

Mixtures of triazine derivatives free from polyalkylene oxide Mixtures of triazine derivatives free from polyalkylene oxide are produced from 20 to 70 percent by weight of triazine derivatives with hydroxyalkyl amino groups and 80 to 30 percent by weight of triazine derivatives with bis(hydroxyalkyl) imino groups by catalytic reaction of alkylpropylene oxides with triazine derivatives at a melamine derivative/alkylpropylene oxide molar ratio of 1:1.5 to 1:10 in the presence of metal alkyls, metal hydrides, metal alcoholates and/or metal alkylamides as catalysts.The triazine derivative/hydroxy group mixtures free from polyalkylene oxide are particularly suited for producing plastic materials, flame retardants, additives, pharmaceuticals, textile auxiliaries, and paints or finishes.
