摘要：<p>This invention relates to a polytriazine characterized as being the reaction product of (a) between 1 and 100 mole percent of an aromatic polycyanate which corresponds to the formula wherein: Ar is an aromatic radical; B is a C7-20 polycyclic aliphatic radical; D is independently in each occurrence any nonactive hydrogen-containing substituent; q, r and s are independently in each occurrence the integers 0, 1, 2 or 3, with the proviso that the sum of q, r and s is greater than or equal to 2; t is independently in each occurrence an integer of between 0 and 4 inclusive; and x is a number between 0 and 5 inclusive, (b) between about 0 and 99 mole percent of one or more cyanate containing compound corresponding to the formula Ar?OCN)n wherein Ar is an aromatic radical and n is an integer of between 1 and 5 inclusive and a process for preparing the above polytriazines. The polytriazines so obtained have good thermal stability, chemical inertness and solvent resistance, the polytriazines are useful in a wide variety of fields including vessel and pipe construction by the winding technique, in electrical engineering, in mold construction and tool making and also in the construction of heavily stressed components, in the lightweight construction of vehicles in aeronautical and astronautical engineering.</p>
