Abstract

Critical micelle temperatures (cmT) of triblock copolymer F88 (nominally E₁₀₂P₃₉E₁₀₂), where E = oxyethylene and P = oxypropylene in aqueous solution were determined by light scattering and eluent GPC (aqueous solvent). Two samples originating from different suppliers (BASF Inc. and ICI plc) were investigated. The overall formulae of the two samples (checked by NMR) were essentially identical, but their GPC curves (THF solvent) differed significantly. Comparison of the cmTs obtained, including published values from a dye solubilization method, showed good agreement between techniques but poor agreement between samples, i.e. differences of 10-15°C across a range of concentrations.
