Abstract

The synthesis of fluoropolymers containing well-defined reactive functional groups such as hydroxy, carboxylic acid, phenol, and amine was reported. The preparation of crosslinked fluorinated polymer networks and nanocomposites with high thermal stability and uniform dispersibility under mild conditions was also demonstrated. The benzoyl peroxide (BPO) derivatives were also obtained through the reaction of functional group substituted benzoic acid with H 2O2 in the presence of N,N'-dicyclohexyl-carbodiimide (DCC). The polymerizations were carried out in acetonitrile in the presence of 0.2 mol % functional initiator at 90°C. Gaseous fluorinated monomers were transferred and condensed through a dual-manifold Schlenk line into an autoclave equipped with a magnetic stirrer. Analysis of the composite thin films by transmission electron microscopy reveals the uniform nature of the films.
