Abstract

Properties of aqueous solution, that is, the viscosities and solubilities of benzene were observed in relation to critical micelle concentration of each alkyl aldehyde polyoxyethylene glycol acetal type surfactant. These showed that the mininum points in specific viscosity/concentration-concentration curves were corresponded with the critical micelle concentration obtained by surface tension and appeared the remarkable increase of non-Newtonics according to the increase of the number of carbon in hydrophobic groups. The fluidity of non-Newtonics is not observed by a little increase of the degree of polymerization in polyoxyethylene glycol groups.
