Nonionic surfactants of the polyethylene oxide type are precipitated by carboxy vinyl polymer (CVP) in its acid form. While the reduced viscosity of the CVP solution is affected more markedly by a surfactant with a longer polyethylene oxide chain, the binding to CVP of the nonionic surfactants with the same hydrophobic parts occurs more effectively with shortening of the polyethylene oxide chain or with lowering of the critical micelle concentration. The structure of the complexes formed is discussed.
