Abstract
Solutions of an ethylene oxide-propylene oxide triblock copolymer (PEO/PPO/ PEO) pluronic(R) P65 (50-50 wt.% of each block with total molecular weight of 3400 g mol(-1)) in aqueous sodium chloride examined by different methods reveal salt-induced micellization. The critical micelle concentrations (CM Cs) and critical micelle temperatures (CMTs) showed a marked decrease in th e presence of added salt. Unimer-to-micelle transitions at low concentratio n (or temperature) and micellar growth at temperature close to cloud point are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
