Water and salt transport properties were determined in a family of sulfonated pentablock copolymers to characterize their potential as chlorine-tolerant desalination membrane materials. The degree of sulfonation, block molecular weight, and casting conditions can be independently varied to tune the transport properties of these materials. Data for water uptake, water permeability, salt permeabi...

Novel cationic pentablock copolymers based on poly(2-diethylaminoethylmethacrylate) (PDEAEM) and Pluronic F127 were evaluated as non-viral gene delivery vectors from a physiochemical point of view for stability and transfection efficiency in complete growth media. A novel strategy was introduced to sterically stabilize the polyplexes of such Pluronic-based cationic polymers against aggregation ...

A unique pH-dependent phase behavior from a copolymer micellar solution to a collapsed hydrogel with micelles ordered in a hexagonal phase was observed. Small-angle neutron scattering (SANS) was used to follow the pH-dependent structural evolution of micelles formed in a solution of a pentablock copolymer consisting of poly((diethylaminoethyl methacrylate)-b-(ethylene oxide)-b-(propylene oxide)...
