Abstract
A polytrimerizable mixture of PA1 30 to 99.9% by weight of at least one aromatic, polyfunctional cyanic acid ester or a prepolymer thereof, and PA1 0.1 to 70% by weight of at least one high-boiling ester with a boiling point above 250.degree. C at 760 Torr, Said mixture results in polytriazines having a significant improvement in elasticity, flexibility and resistance to hydrolysis.
