Abstract

The effect of end-functional group on the phase behavior of block copolymers was analyzed. The effect was studied using small-angle x-ray scattering, transmission electron microscopy (TEM), polarized optical microscopy (POM) and rheology. The molecular weight of polystyrene precursor was measured by size exclusion chromatography. The results show that the addition of only one end-functional group to polystyrene-block-poly(n-butyl methacrylate) changed the lower disordered-to-ordered transition (LDOT).
