実験手順

Zero point zero five part by mass of tetrabutylammonium bromide was added to 100 parts by mass of a bisphenol F type epoxy resin (Epiclon 830), and with stirring the mixture was heated to 175° C. Then, 20 parts by mass of toluene diisocyanate were supplied, taking 3 hours, and the mixture was further stirred at 175° C. for 4 hours, to obtain an isocyanate modification product of the bisphenol F type epoxy resin.
