For the first time, it was shown the cationic miniemulsion polymerization of styrene using an ionic liquid as catalyst. The ionic liquid (BMI.Fe₂Cl₇) was tolerant to the presence of high amount of water, being effective for polymerization of styrene in the evaluated temperatures range from 70 to 90 °C. The polymerization was considerably slower than conventional cationic polymerization, indicating that this process is easier to control than the conventional ones. In addition, quite high molecular weights were reached, while the particle size, between 150 to 175 nm, was within the typical range for miniemulsion polymerization.

咪唑基离子液体介导的苯乙烯阳离子微乳液聚合

首次显示了使用离子液体作为催化剂的苯乙烯阳离子微乳液聚合。离子液体（BMI.Fe ₂ Cl ₇）可以耐受大量水的存在，在70至90°C的评估温度范围内对苯乙烯的聚合反应有效。聚合反应比常规的阳离子聚合反应要慢得多，这表明该方法比常规的阳离子聚合反应更容易控制。另外，达到了相当高的分子量，而粒度在150至175nm之间，在细乳液聚合的典型范围内。
