Abstract
There is provided a method capable of producing a methacrylic-based polymer excellent in pyrolysis resistance and excellent in fabricability in a high productivity. The method for producing a methacrylic-based polymer includes the following steps (1) and (2): step (1) of using a complete mixing reactor (A) to thereby obtain the first syrup, including specific steps; step (2) of using a reaction apparatus (D) including a plug flow mixer (B) and a plug flow reactor (C) to thereby obtain the second syrup, including specific steps.
