Reaction Steps

The diacetate of hydroquinone had a tendency to sublime into the distillation column. It was, therefore, necessary to charge the reactor in such a way so as to make up for this loss of the diacetate of hydroquinone. The highest intrinsic viscosity was obtained when a 1.6% molar excess of hydroquinone diacetate was employed. Air was used to cool the condenser, since water cooling caused more sublimate to form a in the condensation column. Excess sublimate in the distillation path would eventually inhibit the formation of high vacuum in the latter stages of the polymerization reaction.
