Micellization SEBS (original) (raw)

The dilute solution properties of Polystyrene-Poly(ethylene-butylene)-Polystyrene three block copolymer (SEBS) in homologous series of n-alkanes(C 6 -C 16 ) have been studied by means of viscosity. Huggins equation has been employed to determine the intrinsic viscosity of micelles. The temperature dependence of intrinsic viscosity and hydrodynamic radius of SEBS in n-alkanes was observed when temperature varies from 25 o C to 30 o C , above 35 o C the intrinsic viscosity is observed to increase. A great dependence of the hydrodynamic radius and intrinsic viscosity with the carbon number of n-alkane molecules was found at high temperature.
