Abstract

Lyotropic liquid crystalline structures formed by amphiphilic heteroarm star copolymers were investigated. A remarkably rich structural polymorphism was observed in a ternary isothermal system consisting of a PEO-PPO-PEO triblock copolymer water and oil. Size exclusion chromatography, static light scattering, NMR and differential scanning calorimetry were used for polymer characterizations. It was shown that the segregation of the heteroarm star copolymers lead to thicker interfaces than those expected for diblock copolymers due to their specific architecture constraints.
