Properties of dilute solutions of hydrophobicaly modified poly(4-vinyl pyridine) (polysoaps)

摘要

Hydrophobically modified poly (4-vinyl pyridines) by alkyl bromides are kinds of polysoap similar to the surfactant. Properties of dilute solutions were studied through the viscosity measurements in pure water and NaCl solutions. In aqueous solu- tions of polysoaps hudrophobic interaction can be attributed to aggregation of hydrohobic groups of the olysoap main chains. The hydrophobic groups of polysoap can aggregate to form hydrophobic microdomains (micelles) I aqueous solution. This is a compact confor- mation. The formation of such microdomains is a process of dynamic equilibrium.
