测定了聚合动力学和化学稳定性对可见光引发自由基/阳离子开环杂化光聚合固化聚合物的交联结构和力学性能的影响。使用三组分引发剂体系，单体体系包含甲基丙烯酸酯和环氧化物。光聚合动力学监测原位傅立叶变换红外衰减全反射。用调制式差示扫描量热法和动态力学分析研究了交联结构。X射线微计算机断层扫描是用来评估微相分离。由自由基聚合形成的杂化物形成的聚合物的力学性能。这些调查标志着第一次，环氧基和甲基丙烯酸酯的羟基之间的链转移反应的好处，在混合可见光引发的光聚合过程中的交联网络和微相分离，已被确定。
The effects of polymerization kinetics and chemical miscibility on the crosslinking structure and mechanical properties of polymers cured by visible-light initiated free-radical/cationic ring-opening hybrid photopolymerization are determined. A three-component initiator system is used and the monomer system contains methacrylates and epoxides. The photopolymerization kinetics is monitored in situ by Fourier transform infrared-attenuated total reflectance. The crosslinking structure is studied by modulated differential scanning calorimetry and dynamic mechanical analysis. X-ray microcomputed tomography is used to evaluate microphase separation. The mechanical properties of polymers formed by hybrid formed by free-radical polymerization. These investigations mark the first time that the benefits of the chain transfer reaction between epoxy and hydroxyl groups of methacrylate, on the crosslinking network and microphase separation during hybrid visible-light initiated photopolymerization, have been determined.
