(57) [Summary] (Corrected) [PROBLEMS] To provide a hydrolysis-resistant stabilizer for a resin having an ester group, and a method for stabilizing the hydrolysis resistance of a resin having an ester group by the stabilizer. SOLUTION 4,4'-dicyclohexylmethane diisocyanate represented by or a formula Or isophorone diisocyanate represented by A hydrolysis-resistant stabilizer for a resin having a carbodiimide derived from a mixture of 4'-dicyclohexylmethane diisocyanate and isophorone diisocyanate, which has an ester group mainly containing two or more carbodiimide groups in the molecule. |
