Access to the superstrong segregation regime with nonionic ABC copolymers

The access to the superstrong segregation regime (SSSR) with nonionic, flexible coil block copolymers, by use of three-monomers ABC triblock copolymers was discussed. An access to the SSSR consisted of a water soluble poly(ethylene oxide) (O) block, hydrocarbon, polystyrene (S) and a fluorppolymer (F). A linear OSB triblock prepared by controlled anionic polymerization, with block molecular weights of 13200 (N _o=300),4700 (N _s=45) and 1300 (N _b=24. It was observed that a new domain of block copolymers phase behavior, the superstrong segregation regime was accessed in a controled fashion with nonionic triblock copolumers.
