Model and Hybrid Polystyrenes Containing Trispentafluorophenylgermanium End Groups

Abstract

The synthesis of the model functionalized polymers of various molecular weight–containing active pentafluorophenylgermanium end groups was performed through chain-transfer reaction to germanium organic compounds-tris(pentafluorophenyl)germane by a free-radical polymerization of styrene. Upon subsequent activated copolycondensation of the obtained polymers with tris(pentafluorophenyl)germane in methyl ethyl ketone environment in the presence of the activator triethylamine hybrid linear-dendritic the block copolymers of polystyrene and perfluorinated poly(phenylenegermane) were obtained. Molar mass and hydrodynamic characteristics of model and hybrid polymers were studied by the methods of size exclusion chromatography, static and dynamic light scattering, and viscometry.
