摘要：

The association of two block copolymers, hydrogenated polystyrene-poly(methyl methacrylate) (PSH-PMMA) in 1-chloro-n-hexane (a selective solvent for PSH) and deuterated polystyrene-poly(methyl methacrylate) (PSD-PMMA) in dimethyl sulfoxide (a selective solvent for PMMA), has been studied by light and neutron scattering. Unusual large particles are formed in the temperature range corresponding to the theta point of one block of the copolymer whereas small compact micelles are observed at room temperature. At low temperature the results show good agreement with the model of closed association where unassociated molecules are in equilibrium with monodispersive micelles.
