The temperature dependence of crystal growth rate (G) shows a bell shape with the maximum growth rate G_max. The activation energy for the molecular transport in G could be expressed in terms of equation of either Arrhenius or WLF. The G_max showed remarkable molecular weight dependence. The plots of G/G_max against T/T_cmax showed a single master curve without molecular weight dependence. The ratio of G_o/G_max gave a constant value for each polymer. Plots of $\ln (G/G_{max})/\ln (G_o/G_{max})$ against T/T_cmax for various polymers showed the universal curve. The molecular weight dependence of G_max was expressed as $G_{max} \propto MW^\alpha$, $\alpha$ was a constant but depending on the morphological features on the crystallization. The value of $\alpha$ was a function of the adsorption mechanism of polymer molecules on the crystal growth front and its diffusion mechanism. The ratio of T_cmax/T_m^o was formulated. T_cmax was also correlated to many other thermodynamic transition temperatures.
