We report the morphological characterization of asymmetric miktoarm star block copolymers of the (PS-b-PI)nPS type where n=2,3 (denoted 2DB and 3DB miktoarm stars, respectively) and a symmetric super H-shaped block copolymer of the (PS-b-PI)3PS(PI-b-PS)3 type (denoted SH) which were synthesized by anionic polymerization. The initial volume fraction of PS (φPS) for each copolymer was 0.51–0.56, giving...
This work describes a synthesis of linear diblock and triblock copolymers of 2-vinyl pyridine (2VP) and ethylene oxide (EO). The overall synthetic approach involved polymerization of 2VP, followed by polymerization with EO. Neutralization of the reactive end-groups of the living diblock P2VP-b-PEO (-) K (+) produced the diblock copolymer P2VP-b-PEO. Reaction with...
