PURPOSE: A method for preparing resin syrup is provided to prevent mixing failure, overcrowding of reaction, and reaction contamination caused by viscosity rise while using a monomer difficult to apply to the existing bulk polymerization. CONSTITUTION: A method for preparing resin syrup comprises the steps of: preparing a partial polymer of a monomer mixture by performing exothermic bulk polymerization within a reaction system containing a monomer mixture with a glass transition temperature of -20°C or less; and diluting the partial polymerization by injecting the monomer mixture with a glass transition temperature of -45°C or more into the reaction system. The monomer mixture of the first step comprises C4-20 alkyl group-containing alkyl (meth)acrylate. |
