Abstract
Subject headings
Close
- We have investigated the phase diagram of the triblock copolymer P123 solved in water by viscosity measurements for different concentrations and temperatures The structures of the different phases were identified by surface sensitive neutron diffraction We find a pronounced hysteresis between heating and cooling During heating, a highly viscous crystalline fee phase is found before melting occurs at 44 degrees C with a simultaneous drop in viscosity Upon cooling, first a hexagonal phase with low viscosity develops followed by a highly viscous fee phase Phase diagrams for the heating and cooling cycle for different concentrations are provided The hysteric behavior is discussed in relation to the shape of the micelles
