摘要：

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