DICYANATOCHALCONES AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to dicyanatochalcones of general formula (I), wherein R<1> to R<8>, independent of one another, represent hydrogen, C1-C4 alkyl, C1-C4 alkoxy or halogen. The compounds can be produced from corresponding dihydroxychalcones by reacting them with chlorine cyanide or bromine cyanide and with a tertiary amine. The inventive compounds are suited for producing polytriazine resins exhibiting good mechanical properties, a low dielectric constant and a good behavior in fire.
