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
