    • 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 ° C. 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.
    • 本发明涉及通过本体聚合制备丙烯酸酯聚合物浆料的方法,更具体地说,涉及一种制备丙烯酸酯聚合物浆料的方法,其包括以下步骤:将单体溶液和引发剂溶液供应到单体 溶液储层和引发剂溶液储层; 将单体溶液和引发剂溶液供应到完全混合型连续反应器,同时将单体溶液储存器和引发剂溶液储存器中的溶解氧分别维持在0.0001至3ppm,或在供给之前混合; 并连续进行本体聚合,同时将提供给连续反应器的溶液混合物保持在70至150℃和1至10大气压,平均停留时间为30至240分钟。 根据本发明,即使使用少量的引发剂,也可以在低聚合温度下聚合度为20〜70%的丙烯酸酯聚合物糖浆。 通过使用半衰期短的引发剂减少反应时间可以提高生产率,聚合可以非常稳定和连续地进行而没有凝胶化。
