This work reports on a solid-state NMR (SSNMR) methodological approach for the characterization of perfluoropolyether-tetrafluoroethylene block copolymers (PFPE-b-TFE). While solution state NMR was successfully used for the study of PFPE-b-TFE copoly

The oxypolymerization reaction of perfluoro olefins is one of the industrial routes for the synthesis of perfluoropolyethers (PFPEs). The distinctive feature of this radically initiated process is that one obtains peroxidic perfluoropolyethers from t

The synthesis of (per)fluoropolyether phosphate esters prepared by the reaction of phosphorus pentoxide and fluorinated alcohols has been investigated. The reactivity strongly depends on the structure of the fluorinated alcohol, generally decreasing

Publikováno v: Journal of Fluorine Chemistry. 95:71-84

IR and NMR spectroscopies are the most important techniques used to identify and quantify end groups in fluoropolymers. We review here some literature studies about the characterisation of end groups in some fluoropolymers based on tetrafluoroethylen

The kinetic features of vinylidene fluoride (VDF) radical polymerization in solution, initiated by bis(4-butylcyclohexyl)peroxydicarbonate, have been investigated in three different solvents (acetone, ethyl acetate and methyl acetate) under homogeneo
