Synthesis and surface properties of amphiphilic block copolymers polyvinylpyrrolidone-block-polystyrene

Synthesis and surface properties of amphiphilic block copolymers... Amphiphilic block copolymers of N-pyrrolidone and styrene were prepared by chain transfer to organogermanium compounds bis(pentafluorophenyl)germane and tris(pentafluorophenyl)germane. The relative chain-transfer constants were determined. The surface properties of the isolated block copolymers with various numbers of units in the hydrophilic block were studied. The polar and dispersive components of the surface tension of films of the amphiphilic block copolymers were calculated by the Zisman method. Russian Journal of Applied Chemistry Springer Journals
