已经研究了使用高强度超声波作为甲基丙烯酸甲酯聚合引发剂。 结果证实，纯的、干燥的乙烯基单体可以通过该方法聚合，但聚合和降解过程同时发生，因此分子量是超声处理时间的复杂函数。 研究还表明，偶氮化合物等热引发剂可以在室温下分解，为自由基聚合的可控低温引发体系提供了前景。
The use of high intensity ultrasound as an initiator of polymerization in methyl methacrylate has been investigated. The results confirm that pure, dry, vinyl monomers can be polymerized by this method but that there are simultaneous polymerization and degradation processes occurring so that the molecular weight is a complex function of sonication time. It was also shown that thermal initiators such as azo-compounds can be decomposed at room temperature, offering the prospect of a controllable, low temperature initiation system for radical polymerization.
