METHOD FOR PRODUCING LATENT CURING AGENT

摘要

The latent curing agent in which the imidazole compound is held in the porous resin particles is obtained by dissolving the polyfunctional isocyanate compound in an organic solvent in an amount of 1.5 to 5 times by mass and dissolving the water-soluble polypeptide and the surfactant in water, Emulsified, then subjected to interfacial polymerization, further added with a proteolytic enzyme to perform enzymatic decomposition treatment, recovering the porous resin particles, and then impregnating the recovered porous resin particles with an imidazole compound solution.
