Abstract
The invention is a process for making a cyanate ester resin cured product by (1) adding organic metal compound (a) and triethanol amine(b) to a cyanate resin composition which is flowable at a temperature of not more than 50.degree. C. comprising as its main component polyfunctional cyanate ester compound having at least two cyanate groups, thereby forming a cyanate resin composition having 0.1-5% by weight of (a) and 0.1-5% by weight of (b), which is flowable at a temperature of not more than 50.degree. C.; (2) molding the composition at a temperature of not more than 50.degree. C. (3) primary curing at a temperature of not more than 50.degree. C.; and (4) post-curing at a temperature of not less than 170.degree. C.
