Abstract
Abstract Pentafluorophenylmethyldiethoxysilane is an interesting new monomer for preparing fluoropolysiloxanes because of its unusually high fluorine content. It was synthesized using either a bromo- or iodo-Grignard reagent, and its structure was characterized by GC-MS, IR, andlH-NMR. It was polymerized by hydrolysis and condensation reactions to yield poly(pentafluorophenylmethylsiloxane) [-Si(C6F5)(CH3)O-]X, which was characterized by FTIR and 1H-NMR. Its relatively high number-molecular weight, 6.5 × 104 g mol−1, should encourage further characterization studies with regard to unusual properties such as permeability and surface activity.
