研究了在少量聚乙二醇马来酸单酯钠盐存在下， ＭＭＡ／ＢＡ无皂乳液聚合成粒过程， 发现聚合初期产生的初级粒子消失后， 两次周期性地产生小粒子． 经分析， 是新的成核作用产生的，表明在聚合的中晚期， 成核过程并未真正结束， 而是处于成核－聚并的动态平衡之中．
In the presence of a small amount of polyethylene glycol maleate monoester sodium salt, MMA / BA soap-free emulsion polymerization granulation process was found, the primary particles generated after the initial polymerization was found to disappear, the two small particles periodically generated. After analysis, it is a result of a new nucleation, indicating that during the middle and late polymerization, the nucleation process did not really end, but was in the nucleation-aggregation dynamic equilibrium.
