Abstract

A homologous set of linear poly(isoprene-b-styrene-b-ethylene oxide) (ISO) triblock copolymers were investigated. The experiments were conducted above 100 degree C, which exceeded the melting and glass transition temperature. Ordered phases were identified using four techniques - small-angle x-ray scattering, transmission electron microscopy, light polarization and dynamic mechanical spectroscopy (DMS). The polymers were prepared in the weak-to-intermediate segregation regime, that resulted into smoothly varying periodic composition fields, the symmetry of which defined the morphology.
