Synthesis and characterization of model fluorinated block copolymers

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A series of monodispersed polystyrene-b-fluorinated polyisoprene (PS-b-PI) block copolymers was synthesized by the selective insertion of difluorocarbene into the PI block of a preformed PS-b-PI diblock copolymer. The fluorination extent was controlled by the molar ratio of hexafluoropropylene oxide to the double bonds. The narrow molecular weight distribution of the fluorinated products suggested that the polymer chains were modified without side reactions. Small-angle X-ray scattering analysis was used to characterize the morphologies of these novel copolymers. The domain spacings increased significantly with the fluorination extent.
