摘要：

A crystallizable diblock copolymer of polystyrene/hydrogenated polybutadiene (SEB) was prepared by catalytic hydrogenation of a polystyrene/polybutadiene (SB) precursor. Changes in the morphology of SEB were observed following solution casting at temperatures below and above the melting point of the EB block. Annealing of the bulk copolymer also affected the observed morphology. A qualitative phase diagram is presented to place the observations in perspective.Path-Dependent Morphologies of a Diblock Copolymer of Polystyrene/Hydrogenated Polybutadiene. © 1990, American Chemical Society.
