Abstract
Abstract A polymer having a fluorine-containing end group which is produced by polymerizing a monomer capable of radical polymerization in the presence of a fluorine-containing thiol; a vinyl ester polymer having a fluorine-containing end group which is produced by polymerizing vinyl ester in the presence of a fluorine-containing thiol; and vinyl alcohol polymer having a fluorine-containing end group which is produced by saponifying the said vinyl ester polymer; and processes for producing the same are provided. The polymers of this invention are superior in water repellency, oil repellency, heat resistance, chemical resistance, and surface activity which are characteristic of fluorocarbon compounds, and are expected to find use in various application areas.
