Anionic polymerization high vacuum techniques were employed for the synthesis of a diblock (PS- b -P t BuMA) and two triblock (PS- b -P t BuMA- b -PS) copolymers of polystyrene (PS) and poly( t -butyl methacrylate) (P t BuMA) bearing similar low molecular weight PS end-block(s). Dilute solution viscometry, as well as static and dynamic light scattering, were employed to assess whether the short PS end-blocks were able to promote association in t -amyl alcohol, a selective solvent for P t BuMA. The effect of macromolecular architecture on the association behavior of the copolymers was also examined. |
