1. A method for preparing an acrylic ester polymer syrup using a polymerization apparatus comprising a complete-mixing type continuous reactor, a monomer solution reservoir, and an initiator solution reservoir, which comprises the steps of:

  • a) supplying a monomer solution and an initiator solution to the monomer solution reservoir and the initiator solution reservoir, respectively;

    b) supplying the monomer solution and the initiator solution to the 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

    c) performing bulk polymerization continuously while maintaining the solution mixture supplied to the continuous reactor at 70 to 150°

    C. and 1 to 10 atm, with a mean residence time of 30 to 240 minutes.
