抄録

The structural viscosity of the commercial and the synthesized aluminum distear-ate by the double decomposition method in aqueous solution was measured by capilary viscosimeter in benzene. The result was that aluminum stearate in benzene solution showed the structural viscosity at a low concentration of less than 0.5g./100cc., and that the time dependency of apparent viscosity in solution was assumed to be due mainly to the change of molecular weight of aluminum stearate.<br>By applying the double extrapolation method of 1/s→0 and c→0 into in η/r/c the intrinsic viscosity was calculated, and it gave exact information on the property of aluminum stearate. When the molar relationship of the intrinsic viscosity, [ηN] to aluminum and stearic acid was calculated, the maximum of [ηN] was found in a little smaller than 2 of St/Al.
