摘要

<正>The reduced viscosity of polymer guar gum solutions containing a certain concentration of sodium dodecyl benzene sulfonate （SDBS） was measured. It has been found that the Huggins coefficient kH of polymer solutions is very sensitive to the concentration of the surfactant

cSDBS

in solutions. If CSDBS is lower than CMC

the critical micelle concentration of SDBS

kH increases rapidly with CSDBS. On the other hand

if CSDBS is larger than CMC

kH decreases rapidly with CSDBS. Comparatively

the intrinsic viscosity of polymer solution does not show a notable change with CSDBS. The experimental results indicate that the interchain association of polymer guar gum in solution is greatly associated with SDBS interacted with polymer chains through hydrogen bonds. However

the effect of SDBS upon the intrachain association of polymer guar gum solution is negligible

presumably due to the fact that guar gum is a slightly stiffened random-coil chain polymer.
