Chang] Summary: Modified models for the prediction of the slope index of the viscoelastic master curve in the primary transition region for vinyl polymers with either bulky side groups or α-methyl groups have been proposed. Very good agreeements between predicted and experimental values are found. The modified models take into account of the effect of the bulky side group or α-methyl groups in the contribution to the corrected number of the main-chain atoms. The predicted slope index was found to be proportional to (i) the average cohesive energy per main-chain atom; U/N, which represents the enthalpic interchain interaction, (ii) the entropic intrachain interaction as defined by H/N, and (iii) the average spatial molecular volume per main-chain atom V/N.
