摘要

光聚合中许多动力学“反常”现象可以用吸光度的影响来解释。体系吸光度受引发剂浓度、消光系数、体系厚度和入射光波长的影响，因此，这四个因素都会影响光聚合动力学。体系低吸光度时光聚合动力学与热聚合时类似，而在高吸光度时完全不同。

Abstract

Most of the "abnormal" kinetic behaviour in photopolymerization can be explained by absorbance effect in the system. Absorbance depends on the concentration and extinction coefficient of initiator

the thickness of the system and the wavelength of the incident light. So all the four factors will influence the kinetics of photopolymerization. In low absorbance

the kinetics of photopolymerization is similar to that of thermal polymerization

while in high absorbance

they will be quite different.
