A Capacitance Method for Following Vinyl Polymerizations Initiated by γ-Rays

The deficiencies of dilatometric methods for studying vinyl radiopolymerization are pointed out and a capacitance method is described. A mercury column is connected to the reaction vessel and volume changes affect the mercury level as the reaction proceeds. A sheathed steel rod parallel to the Hg co...

Zusammenfassung:The deficiencies of dilatometric methods for studying vinyl radiopolymerization are pointed out and a capacitance method is described. A mercury column is connected to the reaction vessel and volume changes affect the mercury level as the reaction proceeds. A sheathed steel rod parallel to the Hg column is one side of a condenser of which the Hg is the other. A capacitance bridge measures changes in volume thereby. (T.R.H.)
