Abstract
Polystyrene/poly(ethylene oxide) heteroarm star copolymers (i.e., star-shap ed polymers consisting of a central poly(divinylbenzene) core bearing an eq ual number of short polystyrene and long poly(ethylene oxide) arms, PS10PEO 10) were synthesized by anionic polymerization, and their phase behavior wa s investigated in aqueous solutions as well as in water-oil solvent mixture s. Because of their amphiphilic character and despite their star architectu re, these polymeric species self-assemble under equilibrium conditions into lyotropic liquid crystalline structures.
