    Notes: The equilibration of water between aqueous gelatin solution and physically separate cakes of ice was observed. Typically, the water content of the solutions reached a nearly steady value several times before final equilibrium, reasons for which are discussed. The equilibrium gelation concentrations were found to be 72 ± 1%, 77 ± 2%, and 80 ± 3% at -10, -21, and -33°C., respectively, in moderately good agreement with predictions based on the vapor pressure measurements of Bull at higher temperatures.

    Description / Table of Contents: Die experimentellen Bedingungen, die zur Steigerung der Reaktionsgeschwindigkeit durch Anlegen eines elektrischen Feldes angewandt wurden, wurden überprüft. Die im System fließenden Ströme und die Größe der elektrolytischen Effekte wurden abgeschätzt. Nimmt man für anionische Systeme an, daß ein Elektron ein «lebendes» Ende produziert oder zerstört, so ist der elektrolytische Effekt beträchtlich und kann über 50% der «lebenden» Enden bei Systemen mit hoher Verdünnung erfassen. Ausgehend von einer Kontroverse über Experimente mit einem periodisch wechselnden Feld werden, die Unterschiede des Einflusses des elektrischen Feldes bei anionischen und kationischen Systemen diskutiert.
    Notes: The experimental conditions employed for rate enhancements by field effects have been examined. An estimate of currents flowing in the systems has been made and the magnitude of electrolytic effects estimated. For living anionic systems, if the passage of electrolytic current is assumed to produce or destroy one living end per electron flowing, the magnitude of the electrolytic effect is significant and may range over 50% of the living end concentration for systems of high dilutions. The differences between electric field effects in living anionic and cationic polymerizations are discussed particularly with reference to the recent controversy over periodic field reversal experiments.
