PROBLEM TO BE SOLVED: To obtain a viscous liquid by a simple method without the blocking of a polymer in a liquid feed line at the bottom of a stirring tank. SOLUTION: In the method for producing a methacrylic-based viscous liquid, a polymer including a methyl methacrylate unit and a monomer including methyl methacrylate are mixed together. When the polymer is dissolved in the monomer by being heated with stirring, gas is intermittently introduced from the liquid feed line. COPYRIGHT: (C)2011,JPO&INPIT
