摘要

SUMMARY OF THE INVENTION [;R_One-NCN-R₂(One);OCN-R₃-(NCN-R₄) n-NCO (2);R₅-NCN-R₆-(NCN-R₇) n-NCN-R₈(3), or formula;R₉-R₁₀-(NCN-R₁₁) n-R₁₂(4);, A carbodiimide compound represented by the general formula (1) as a main component, a drug for improving resistance to deterioration of a resin having an ester group by microorganisms,;Any one or plural kinds of the carbodiimide compounds represented by the above-mentioned formulas (1) to (4) may be mixed with a resin containing an ester group or reacted with a part of the ester group-containing resin. The constitution of the resin composition having resistance to deterioration by microorganisms can be obtained by mixing any one or plural kinds of the carbodiimide compounds represented by the above-mentioned formulas (1) to (4) in a resin containing an ester group, The resin having an ester group is reacted with a part of the resin to be subjected to the polymerization reaction.;The resistance-enhancing agent according to the present invention, when added to an ester group-containing resin, can impart tolerance to deterioration by microorganisms.
