    • 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.
    • 本发明涉及对应于式“IMAGE”的多芳族氰酸酯,其中Ar是芳族基团; B是C7-20多环脂族基团; D在每次出现时都是独立的任何非活性含氢取代基; q,r和s在每次出现时独立地为整数b 0,1,2,1或b 3l; 条件是q,4和s之和大于或等于2; t在每次出现时独立地为约0和4之间的整数; x是包括0和5之间的数字。 本发明的另一方面是一种新的聚三嗪,其包括本发明的多芳族氰酸酯的反应产物。 新颖的三叉嗪可以进一步包括本发明的新型多芳族氰酸酯与本领域已知的用于制备聚三嗪的其它氰酸酯的混合物的反应产物。
