A process for the preparation of a polymer nanoparticle by a photoinduced emulsion polymerization includes preparing an emulsion comprising at least one surfactant, a dispersed phase and a continuous phase. The dispersed phase comprises at least one polymerizable monomer and the continuous phase comprises water and at least one photoinitiator. The at least one polymerizable monomer is polymerized by exposing the emulsion to an electromagnetic radiation having a wavelength so as to induce a generation of radicals from the at least one photoinitiator. The at least one photoinitiator is selected from at least one compound of formula (I)
通过光诱导乳液聚合制备聚合物纳米粒子的方法包括制备乳液,该乳液包括至少一种表面活性剂、分散相和连续相。分散相包括至少一种可聚合单体,连续相包括水和至少一种光引发剂。至少一种可聚合单体通过将乳液暴露于具有波长的电磁辐射而聚合,以诱导至少一种光引发剂产生自由基。至少一种光引发剂从公式(I)中的至少一种化合物中选择。
