FLUORINE-CONTAINING POLYMER, PROCESS FOR PRODUCING THE SAME AND CURABLE RESIN COMPOSITION COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a fluorine-containing polymer having an ethylenically unsaturated group that uses an inexpensive raw material having good availability, reduces the burden on equipment and enables stably introducing an ethylenically unsaturated group into a fluorine-containing polymer containing a hydroxy group at a sufficiently high degree of conversion, to provide the fluorine-containing polymer and to provide a curable resin composition comprising the fluorine-containing polymer.

SOLUTION: The process for producing a reactive fluorine-containing polymer comprises permitting a compound having an ethylenically unsaturated group and a carboxylic group to act on a fluorine-containing polymer containing a hydroxy group to conduct an esterification reaction in the presence of an acid catalyst. In addition, the process for producing a fluorine-containing polymer includes a step of separating a solution of the fluorine-containing polymer into at least one organic layer having the fluorine-containing polymer dissolved therein and at least one organic layer other than the aforementioned organic layer to separately take out the fluorine-containing polymer. The fluorine-containing polymer produced by either of these production processes is provided. The curable resin composition comprising the fluorine-containing polymer is provided.
