<P>PROBLEM TO BE SOLVED: To provide a simpler method as a method for producing a composition containing a polycondensate of aniline with acetone, wherein the content of a primary amine is 1 pt.mass or less based on the total 100 pts.mass of a condensate of aniline with acetone and a polycondensate of aniline with acetone. <P>SOLUTION: The method for producing the composition containing the polycondensate of aniline with acetone, where the content of the primary amine is 1 pt.mass or less based on the total 100 pts.mass of the condensate of aniline with acetone and the polycondensate of aniline with acetone, includes a step of bringing an isocyanate group-containing compound into contact with a mixture including the condensate of aniline with acetone and/or the polycondensate of aniline with acetone, and at least 2 pts.mass of the primary amine based on the total 100 pts.mass of the condensate and the polycondensate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
