Sodium bicyclic[2,2,1]heptane dicarboxylate (HPN-68) is a highly effective commercial isotactic polypropylene (iPP) nucleating agent. In this paper, isothermal crystallization behaviors of iPP nucleated with HPN-68 were investigated using differential scanning calorimetry (DSC). The calculation model of Lamberti based on the Avrami method was used for obtaining nucleus density from calorimetric crystallization curves recorded under isothermal conditions. A number of growth rate data have been obtained with the Lauritzen and Hoffman equation. Ge...
