| Abstract: | Measurements of the spherulitic growth rates of bisphenol-A Polycarbonate plasticized with pentaerythritol tetranonanoate (PETN), trimellitic acid tri(n-octyl-n-decyl)ester (TMDO), and tritolyl phosphate (TTP) are reported. The incorporation of a plasticizer enlarges the crystallization range, decreases the temperature of maximum growth rate and accelerates the kinetics to a considerable extent. The growth-rate parameters are calculated from a least-squares analysis of the experimental data according to the kinetic theory of Hoffman and Lauritzen. From the growth-rate data given here and the overall crystallization kinetics reported previously, concentrations of seeds inducing the crystallization were determined. |
