A curable composition is prepared by reacting (1) an alkenylphenyl cyanate or mixture thereof, (2) an aromatic polycyanate, polycyanamide or mixture thereof and (3) a polymerizable ethylenically unsaturated material or mixture of such materials. Said curable compositions provide polymeric (cured) compositions with improved mechanical strength relative to cured aromatic polycyanates and/or polycyanamides.
