    Abstract

    The temperature- and concentration-dependent aggregation of EO(78)PO(30)EO(78) triblock copolymer in aqueous solutions has been studied in the concentration range from 5 to 200 g/dm(3) at 25 degrees C, 45 degrees C and 60 degrees C. The influence of o-xylene on the micellization was measured at various (from 5 to 40) molar ratio of additive to polymer. The aggregates were described as polydisperse spheres with tethered Gaussian polymer chains. The results of the least-squares fit is briefly discussed. (C) 2000 Elsevier Science B.V.
