The conformational behaviour of styrene-p-chlorostyrene diblock copolymers in dilute solutions was studied and compared with that of the corresponding triblock copolymers. Eight styrene-pchlorostyrene diblock copolymers, of almost equimolar composition but with different molecular weights, were prep

Micellar behaviour of styrene (ethylene oxide) copolymers was studied in water and mixed solvent systems (tetrahydrofuran-water and 2-propanol-water) by using photon correlation spectroscopy (PCS), viscosity and turbidity methods. Detailed viscosity measurements were carried out to explain the solut
