摘要：
Provided are a polycarbodiimide compound and a polyester resin composition and polyester resin modifier using the polycarbodiimide compound, the polycarbodiimide compound having a small amount of residual amine and having good processability when the polycarbodiimide compound is added to the polyester resin while keeping hydrolysis resistance of polyester resin imparted thereto through addition of the polycarbodiimide compound. A polycarbodiimide compound represented by the following general formula (1): R m NH 2-m -CO-NH-Z-(N=C=N-Z) n -NH-CO-NH 2-m R m (1) is used, wherein R m is a hydrocarbon residue of an amine compound which is represented by R m NH 3-m and has a boiling point at 1 atm of 150°C or lower; m is 1 or 2; Z is a residue obtained by removing two isocyanate groups from an aliphatic diisocyanate compound; and n is any integer of 2 to 7.
