METHOD FOR PRODUCING CURED PRODUCT OF EPISULFIDE-BASED RESIN

摘要

The present invention can provide a method for producing a cured product of an episulfide-based resin, the method having: (A) a step for obtaining a composition for a resin by mixing compound (a), compound (b) and a polymerization catalyst; (B) a step for pouring the composition for a resin into a mold; and (C) a step in which, by increasing the temperature of a heating medium, the composition for a resin is polymerized in the heating medium that contains a liquid having a thermal conductivity of 0.2 W/m·K or higher, or in a shower of the heating medium. The maximum temperature of the heating medium in step (C) is 55 to 110°C. (a) A compound which has two episulfide groups per molecule and which is represented by formula (1):
wherein m represents an integer from 0 to 4 and n represents an integer from 0 to 2 (b) A compound having one or more thiol groups per molecule.
