- Abstract
- Using 2D-LC, a mother PS-b-PI diblock copolymer prepared by anionic polymerization was fractionated into nine fractions differing in the PI and PS block lengths. In this way, PS-b-PIs of the similar molecular weight were obtained. The fractions show composition variation large enough to construct a detailed phase diagram over ca. 10% composition range. In both molecular weight and composition of the fractions, sharper OOT phase boundaries and better-defined morphologies were observed.
