Abstract
Molecular weight fractionations of binary mixtures of poly(α-methylstyrene)s having narrow molecular weight distributions were carried out by the methods of successive precipitational fractionation and successive solutional fractionation (column fractionation). The amount of polymer, its average molecular weight and the weight ratio of two components in the fraction were determined and the molecular weight distribution curve was constructed. The molecular weight distribution curves as well as the fractionation results were compared with the computer simulation of Kamide et al. The simulation results agreed well with the experimental results provided the concentration dependence of the thermodynamic interaction parameter in the theory of Flory–Huggins was taken into consideration.
