| Abstract: | The ESR spectra of PMMA in bulk polymerization process have been obtained and simulated by using the models of Gaussian distribution about the two stable conformations A and B. The results show that both the ratio of A and B conformations, and the average tilt angle of B conformation decreased with half-height width of the Gaussian distribution as the indicative of the microviscosity of reaction system. The change was discussed with respect to the thermodynamics and dynamics. |
