A new phosphine is proposed as efficient coinitiator for camphorquinone (CQ)-based photoinitiating systems for the free radical polymerization of (meth)acrylates. Remarkably, this new co-initiator can exhibit two functionalities: a phosphine moiety to overcome oxygen inhibition and an iodonium salt moiety as counter cation to initiate the polymerization process. Excellent polymerization performances in the presence of CQ for the free radical polymerization of methacrylates under blue light are observed, and amine-free systems can be easily developed from the proposed structure. The photopolymerization of composites is also investigated in the presence of the new phosphine (without iodonium counter cation) and very interesting depth of cure can be obtained from the new developed photoinitiating system after only 20 s of irradiation with a blue light-emitting diode.

在空气中高效自由基聚合的新型膦。

提出了一种新的膦作为高效的基于樟脑醌（CQ）的光引发体系的共引发剂，用于（甲基）丙烯酸酯的自由基聚合。值得注意的是，这种新的共引发剂可表现出两种功能：克服氧抑制作用的膦部分和作为抗衡阳离子的碘鎓盐部分，以引发聚合过程。在蓝光下，在甲基丙烯酸酯的自由基聚合反应中，在CQ存在下观察到了优异的聚合性能，并且从所提出的结构可以轻松开发出无胺体系。
