According to the theory of solutional fractionation, simulation analyses were carried out for the fractionation of polypropylene and polyethylene. The results were compared with the experimental ones, which were obtained in fractionating 100‐g samples. The experimental results were sufficiently explained by simulation. This fact demonstrated that these fractionations were carried out in the partition equilibrium between two liquid phases. Further, experimental conditions to obtain narrow distribution fractions were investigated by simulation techniques.
