摘要
研究了不同温度(30℃、40℃、50℃)、不同盐水浓度(1％、3％、5％(质量百分数))条件下,吐温(Tween)／正丁醇-甲基丙烯酸甲酯(MMA)-水(或盐水)拟三元体系三相图,并对甲基丙烯酸甲酯微乳液进行了聚合反应研究。研究表明:①随着温度升高,微乳区间增大;②盐类物质的加入对甲基丙烯酸甲酯在微乳液中有增溶效应;③甲基丙烯酸甲酯微乳液聚合反应速率随着温度升高而增大。
The difference between the three phase diagrams of the tween/the n-butyl alcohol - methyl methacrylate - salt water system has been studieded at 30℃, 40℃ and 50℃,the salt water density was 1%, 3%, 5%（ m/m ）. The dynamics of polymerization of methyl methacrylate have been studied in microemulsion. The result shows that ：（1）salt has the effect of increasing solubility of methyl methacrylate in microemulsion;（2）the polymerization speed of styrene has been raised with the initiator amount increasing in mlcroemulsion;（3）the polymerization speed of methyl methacrylate has been raised with the polymerization temperature in microemulsion .
