Synthesis and solvent-dependent micellization of the amphiphilic block copolymer poly(styreneboronic acid)-block-polystyrene

The amphiphilic organoboron block copolymer poly (styreneboronic acid)-block-polystyrene (PSBA-b-PS) has been prepared through a postpolymerization modification route from the silicon-functionalized block copolymer poly(4-trimethylsilylstyrene)-block-polystyrene (PSSi-b-PS). PSBA-b-PS is obtained th...

Description
Summary:The amphiphilic organoboron block copolymer poly (styreneboronic acid)-block-polystyrene (PSBA-b-PS) has been prepared through a postpolymerization modification route from the silicon-functionalized block copolymer poly(4-trimethylsilylstyrene)-block-polystyrene (PSSi-b-PS). PSBA-b-PS is obtained through highly selective reaction of PSSi-b-PS with BBr₃ at room temperature and subsequent hydrolysis of the BBr₂-functionalized intermediate. Transmission electron microscopy studies demonstrate that PSBA-b-PS undergoes pH dependent micellization in aqueous solution. Different morphologies could be realized by using different mixtures of water and organic solvents.
