Synthesis of functional perfluorinated resins, branched perfluorinated ethers and perfluoroalkanoyl fluorides
Abstract
Functional-group-containing perfluorinated resins have been prepared by carefully controlled direct fluorination of poly-(3-methyloxetane-3-methanol). Branched perfluorinated ethers such as bis(perfluoroneopentyl) ether and perfluoro-(2,2-dimethylbutyl methyl ether) have also been synthesized by direct fluorination of alkanols. The by-products, perfluoroalkanoyl fluorides, are useful intermediates.
