  • Publication number: 20220049056
    Abstract: A process for the manufacture of a degradable polycyanurate bulk molding composition includes: contacting a liquid cyanate ester monomer with an additive material and a polymerization catalyst to form a reaction mixture; maintaining a temperature of the reaction mixture at about 80° C. to about 100° C. to form a polycyanurate product having a viscosity of about 120 to about 200 centipoise at 23° C.; heating a reinforcing filler at a temperature of about 50 to about 150° C. to form a pre-heated reinforcing filler; and blending the polycyanurate product with the pre-heated reinforcing filler to form the degradable polycyanurate bulk molding composition. The bulk molding composition can be used to form a degradable polycyanurate article.
