摘要

PCT No. PCT/EP94/02980 Sec. 371 Date May 1, 1996 Sec. 102(e) Date May 1, 1996 PCT Filed Sep. 7, 1994 PCT Pub. No. WO95/07268 PCT Pub. Date Mar. 16, 1995Tris-(cyanato)-s-triazines having the formula: one another, represent halogen, in particular, chlorine, bromine and fluorine, hydrogen or a methyl group or ethyl group. The monomers disclosed always provide an anisotropic network. Methods for the polycyclotrimerization of polycyanates to obtain the inventive compounds are also disclosed.
