Polymer of 1200 molecular weight was prepared from tetrahydrofuran by using a catalyst mixture of ethylene oxide, BF 3 , and water. Fractionation was accomplished by washing a cyclohexane‐toluene solution with mixtures of methanol and water. Results, plotted on Poisson probability paper, showed that the distribution is somewhat broader than the Poisson.
