Poly(oxatetramethylene) glycol. II. Molecular weight distribution

Authors


Abstract

Polymer of 1200 molecular weight was prepared from tetrahydrofuran by using a catalyst mixture of ethylene oxide, BF3, 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.
