<P>PROBLEM TO BE SOLVED: To provide a more simplified method for producing a composition containing a 2,2,4-trimethyl-1,2-dihydroquinoline polymer in which the content of primary amine with respect to the total weight of the composition is 1 mass% or less. <P>SOLUTION: This method for producing a composition containing a 2,2,4-trimethyl-1,2-dihydroquinoline polymer in which the content of primary amine with respect to the total weight of the composition is 1 mass% or less, includes a process of bringing a mixture containing 2,2,4-trimethyl-1,2-dihydroquinoline and a polymer thereof and, with respect to 100 pts.mass total thereof, 2-6 pts.mass of a primary amine, into contact with 3-10 moles of a dicarboxylic acid with respect to 1 mole of the primary amine. <P>COPYRIGHT: (C)2013,JPO&INPIT |
