光固化阳离子活性稀释剂研究进展

随着光固化技术的发展，当前广泛使用的自由基光固化逐渐显示出一些弊端，与自由基光固化相比，阳离子光固化逐渐显示出其固有的优势，如体积收缩小、附着力强、无氧阻聚等。活性稀释剂作为阳离子光固化配方中的重要组成，对配方的固化及最终产品的机械物理性能具有显著影响，因此开发可快速固化的活性稀释剂具有重要的意义。本文介绍了阳离子活性稀释剂的作用原理及特点，并对其发展前景和方向进行了展望。

Research Progress of Cationic Reactive Diluents for Photopolymerization

With the development of photopolymerization technology, the wide use of free radical photopolymerization had exhibited some drawbacks gradually. Compared with free radical photopolymerization,cationic photopolymerization exhibits several inherent advantages, such as, low shrinkage, strong adhesion, no oxygen inhibition, and so on. Reactive diluentas are one of important formulations of cationic photopolymerization, which has a notable effect on curing of formulations and the mechanical properties of the final product. So, exploiting reactive diluent with rapid curing has a vital significance. This paper introduces the mechanisms and properties of cationic reactive diluents. And the prospect and research directions of it are also presented.
