Polysoap solubilization effects

Alternatively, the geometrical effects on solubilization sites can be explained by a simple excluded volume effect, forcing the probe closer to the micellar surface in tail end geometry. This explanation is supported by the findings that rather high polarities were observed for a number of vinylic polysoaps of the tail-end type in comparison to their monomers [64, 65, 74, 164, 245]. In contrast, polysoaps of the head type may show similar or even less polar environments than analogous monomers [152, 167, 187]. 

Most notably, the solubilization capacity of polysoaps is not correlated with their surface activity [78, 343], Thus any combination of these two properties can be realized in polysoaps, even unusual ones such as low surface activity with high solubilization capacity. The phenomenon is not understood, but might be related to different conformations taken at the gas-water interface and in solution (cf. Sect. 6.1), or to cosurfactant effects of the solubilizates. 

A quantitative evaluation of the effects of the degree of polymerization on the properties of polysoaps was undertaken for the phase diagrams of polymeric lyotropic liquid crystals. Here the property shifts level off within a degree of 10-15 (Fig. 44) [126,451], This value may serve as a first approximation, but, as additional studies, e.g. on viscosity, surface tension or solubilization are missing, more studies are needed. 

Organic molecules with limited water solubility were solubilized by those poly soaps for which viscosity studies indicated micellar behavior (6). The solubilization had varied effects on the viscosity of the polysoap solutions, depending on the nature of the solubilized compound and the concentration...
