| 摘 要： | 以一种新的Ｙ型乳化剂１２－丁酰氧基－９－十八烯酸（ＢＯＡ），制备了甲基丙烯酸甲酯（ＭＭＡ）含量高达２０％的微乳液，并以油溶性引发剂偶氧二异丁腈（ＡＩＢＮ）引发其聚合。实验表明，与单体含量较低的微乳液聚合相比，ＭＭＡ在其含量较高的微乳液中聚合时表现出一些明显不同的特征，如在聚合初期，聚合主要在大粒子内进行。ＭＭＡ的 聚合与非极性单体的微乳液聚合相比也比较特殊，其聚合速度和聚合物分子量与引发剂浓度、单

| Abstract: | Methyl
methacrylate microemulsion was stabilized with 12-butinyoxyl-9-octadecenoic acid (BOA),
and the microemulsion with 20% MMA remained clear when it was initiated with AIBN. Through
observing the variation of the polymer particle size, it was found that when conversion
was lower than 30%, the polymerization occurred in the large polymer particles swollen
with monomer. While at higher conversion, the monomer-swollen micelles became the main
loci of polymerization, and the number of total particles increased rapidly by about 20
times. |
