摘要： The present invention relates to a method for preparing an acrylic ester polymer syrup by bulk polymerization, and more particularly, to a method for preparing an acrylic ester polymer syrup, which comprises the steps of: supplying a monomer solution and an initiator solution to a monomer solution reservoir and an initiator solution reservoir, respectively; supplying the monomer solution and the initiator solution to a complete-mixing type continuous reactor, while maintaining the dissolved oxygen in the monomer solution reservoir and the initiator solution reservoir at 0.0001 to 3 ppm, separately or after mixing prior to the supply; and performing bulk polymerization continuously while maintaining the solution mixture supplied to the continuous reactor at 70 to 150 0C and 1 to 10 atm, with a mean residence time of 30 to 240 minutes. In accordance with the present invention, an acrylic ester polymer syrup can be obtained with a degree of polymerization of 20 to 70 % at a low polymerization temperature, even with a small amount of initiator. Productivity can be improved by reducing reaction time with the use of an initiator having a short half-life and polymerization can be performed very stably and continuously without gelation.
