Reaction Conditions

Reaction Steps

In the same reaction vessel as in Example 1 was fed 270 g of the modified polyamine synthesized in Production Example 1 (corresponding to the modified polyamine based on 1 mol of metaxylene, 0.125 mol of methoxypolyethylene glycol and 0.14 mol of epichlorohydrin), and then 186 g (1 mol) of 2-ethylehexyl glycidyl ether (epoxy equivalent of 186, produced by NOF Corporation, the trademark "Epiol EH") was added dropwise thereto over one hour at 80° C. in an atmosphere of nitrogen under stirring. After the completion of the dropwise addition, the reaction was carried out for one hour at a reaction temperature raised 100° C. Then, the vessel interior was cooled to 80° C., and then 231 g (1.70 mol) of metaxylylenediamine was added thereto. Then, a mixture of 307 g (0.807 mol) of epoxy resin in a liquid form of bisphenol A type (epoxy equivalent 190, produced by Yuka Shell Epoxy Co., Ltd., the trademark "Epicoat 828) with 278 g (2.1 mol) of butyl glycidyl ether (epoxy equivalent of 132, produced by NOF Corporation, the tradmark "Epiol B") was added dropwise thereto over one hour at 80° C.
