【Abstract】 WT5BZ]According to the criterion reported by Turner,the factors affecting the critical conversion X 1 transited from low conversion stage to gel effect stage and the expression for use in the correlation of X 1 are determined.With the use of this expression to correlate X 1 data presented in part(1) of this study,the general correlation for predicting X 1 is obtained for MMA and St bulk polymerization.Because the X 1 data of EMA can be also treated with the same expression,it shows that the expression has the universality to correlation of X 1 for polymerization systems of other monomers.If the limiting conversion proposed in literature would be corresponding to the critical conversion X 2 transited from gel effect stage to glass effect stage in the three stage polymerization model,X 2 should also be only a function of reaction temperature.With the use of reaction temperature of correlate X 2 data presented in part(1) of this study,the general correlation for predicting X 2 are obtained for MMA and St bulk polymerization.The kinetic experimental data found in literature are compared with the predictions of the TSPM,the agreement is excellent.
