<P>PROBLEM TO BE SOLVED: To provide a method for producing a resin composition by melting and kneading a carbodiimide compound and a polymer having an acid group, in which the both components are melted and kneaded without suffering from thermal denaturation, degradation or the like, and a free isocyanate does not emit during the process. <P>SOLUTION: A compound having one carbodiimide group and containing a cyclic structure where the first nitrogen and the second nitrogen in the group are bonded by a bonding group is added in the polymer having an acid group brought into a molten state in advance, and melting and kneading for 0.1 minute to 2 hours. <P>COPYRIGHT: (C)2012,JPO&INPIT |
