摘要: 研究初级自由基扩散导致的引发剂"笼蔽效应",考虑到其为非稳态过程,并根据自由体积理论,对"笼蔽效应"给出了微观动力学解释,讨论了引发剂、单体对引发效率的影响,并给出对经典动力学处理相应的适用范围.

关键词: 引发效率, 笼蔽效应, 自由体积, 扩散

Abstract: Considering that the diffusion phenomena of primary radical, which leads to the "cage effect" of initiator, is an unsteady process, we proposed an interpretation for this phenomena microscopically based on the free volume theory. The effects of initiator and monomer on the initiator efficiency are considered, then the applied range of classic theory fitting was given.

Key words: Initiator efficiency, Gage effect, Free volume, Diffusion
