dc.description.abstractIn the present study, diblock copolymers of PS-b-PEO synthesized by sequential living anionic polymerization as well as the blends of PS, PEO homopolymers will be investigated by using liquid chromatography at critical conditions. Critical conditions will be established for the PS block of the copolymer. At these conditions, the PS block is chromatographically invisible and does not contribute to retention so the block copolymer is separated according to the block length of the PEO block. At the critical conditions of PS, it is also possible to separate the PS homopolymer formed. The critical conditions will be established in such a way that the non-critical PEO block elutes in size exclusion chromatography (SEC) mode. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
