Abstract
The present invention provides the process for preparing a fluorine-containing polymer which can easily and efficiently separate a fluorine-containing polymer and water from an aqueous dispersion of a fluorine-containing polymer, and the fluorine-containing polymer obtained by the mentioned preparation process. Further the present invention provides the molded article obtained by crosslinking a curable composition comprising the above-mentioned fluorine-containing polymer and a crosslinking agent. The preparation process is a process for preparing a fluorine-containing polymer comprising a step for heat-treating an aqueous dispersion of a fluorine-containing polymer having a concentration of 3 to 70% by weight to obtain the fluorine-containing polymer having a water content of not more than 1% by weight.
