摘　　要：基于均匀设计方法对甲基丙烯酸甲酯(MMA)的分散聚合反应进行了试验设计,并通过回归分析,建立了聚甲基丙烯酸甲酯(PMMA)粒子相关性能参数(PMMA相对分子质量、粒径大小及分布)和各变量(单体质量分数、稳定剂用量、引发剂用量和反应介质溶度参数)之间的回归方程。根据回归方程进行了分散聚合反应的配方优化,得到了约束条件下的MMA分散聚合反应配方,实测值与预测值比较结果表明,回归方程的预测值与优化配方制备的PM-MA粒子的各项性能实测值之间的相对偏差在10%以内,对试验配方设计有指导作用。In this paper, the uniform design methods were used to arrange four- factor and eight -level experiment of dispersion polymerization of methyl methacrylate, The stepwise regression technique was adopted to analyze the test results and establish the mathematical modes between parameters of PMMA （molecular weight, size and size distribution） and four influencing factors （i. e. monomer concentration, initiator concentration, stabilizer concentration and ratio of alcohol and water）, and their reliabilities were evaluated. Although the predicted values from regression equation were different from the observed values （relative divergences were less than 10% ） , the regression equation could be used for design of PMMA particles and mechanism research.
