There are provided a resin additive with which the generation of an isocyanate gas during the production of a master batch or a resin composition can be effectively suppressed when a carbodiimide compound is used as an additive for improving the hydrolysis resistance of a resin, a master batch using the above resin additive, and a method for producing the same, and a resin composition using the above resin additive, and a method for producing the same. A resin additive comprising a carbodiimide compound (A) and a surfactant (B), and a master batch and a resin composition comprising the above resin additive and a resin (D), and methods for producing these. |
