    • This invention relates to a polyaromatic cyanate which corresponds to the formula ##STR1## wherein Ar is an aromatic radical;B is a C.sub.7-20 polycyclic aliphatic radical;D is independently in each occurrence any non-active hydrogen-containing substituent;q, r and s are independently in each occurrence the integers b 0, 1, 2, l or b 3l ; with the proviso that the sum of q, 4 and s is greater than or equal to 2;t is independently in each occurrence an integer of between about 0 and 4 inclusive; andx is a number between about 0 and 5 inclusive.Another aspect of this invention is a novel polytriazine which comprises the reaction product of the polyaromatic cyanate esters of this invention. The novel polytriazines may further comprise the reaction product of the novel polyaromatic cyanates of this invention in admixture with other cyanates known in the art as useful for the preparation of polytriazines.
