<P>PROBLEM TO BE SOLVED: To provide a method for producing (meth)acrylic polymer, the method producing, with high productivity, (meth)acrylic polymer which is excellent in resistance to thermal decomposition. <P>SOLUTION: The method for producing (meth)acrylate polymer includes a process in which a monomer group which contains (meth)acrylate monomers is subjected to radical solution polymerization. In the process, a chain-transfer agent is added to the polymerization system of the polymerization when the polymerization reaction in the polymerization system is in progress and the polymerization conversion rate, by the reaction, of the polymerization system is at least 60 wt.% and at most 92 wt.%. A (meth)acrylic polymer having a cyclic structure on its main chain may be produced by this production method. For example, the cyclic structure is at least one selected from an N-substituted maleimide structure, maleic acid anhydride structure, glutarimide structure, glutaric acid anhydride structure and lactone ring structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
