（甲基）丙烯酸树脂组成物之制造方法;METHOD FOR PRODUCING (METH) ACRYLIC RESIN COMPOSITION

摘要

本发明为一种(甲基)丙烯酸树脂组成物之制造方法，其系具有：控制甲基丙烯酸甲酯等的量，而将该等连续供给至槽型反应器，在该槽型反应器内进行块状聚合，而得到反应生成物，由反应生成物回收含有甲基丙烯酸甲酯等的混合物(A)，及将该混合物(A)连续供给至前述槽型反应器之步骤；对槽型反应器的甲基丙烯酸甲酯等的供给量控制是根据供给至槽型反应器的混合物(A)的量、以及混合物(A)中的甲基丙烯酸甲酯等的比例来进行，且槽型反应器的完全混合时间、在槽型反应器内的温度下的自由基聚合起始剂的半衰期、槽型反应器的搅拌动力、槽型反应器中反应原料的平均滞留时间及反应原料中的自由基聚合起始剂浓度满足特定关系。; wherein the control of the feed amount of methyl methacrylate and the like to the tank reactor is performed on the basis of the feed amount of the mixture (A) to the tank reactor and proportion of methyl methacrylate and the like contained in the mixture (A), and a perfect mixing time of the tank reactor, a half-life of a radical polymerization initiator at the temperature in the tank reactor, an agitation power of the tank reactor, a mean residence time of the reactant solution in the tank reactor, and a concentration of the radical polymerization initiator in the reactant solution meet the specific relation.
