Capillary Chromatography of Polyvinyl Acetate Emulsions

Abstract

Polyvinyl acetate emulsions stabilized with soap have a considerable resistance against the coagulation due to the addition of sodium sulfate solution. These coagulation behaviours have been easily observed by means of capillary chromatography.
In case of emulsions stabilized with nonionic soaps of polyethylene oxide type, the stabilization effect was found to increase with increase in chain length of ethylene oxide in the soap, and also found that lauryl ether type soaps had better effect on the stability than nonylphenyl ether type.
