Abstract
The effects of poly(ethylene glycol)s of different molecular weights on the micellar stability of sodium dodecyl sulfate in the concentration range fr om 50 to 600 mM were investigated. The presence of polymer was found to dec rease micellar stability drastically. The decreased stability of micelles i s explained by the increased population of small aggregates in the presence of polymer. This decreases the value of "resistance" for the micellar form ation-dissolution process. The foaming property of SDS solutions in the pre sence of poly(ethylene glycol) was related to micellar stability.
