(57) [Summary] [Structure] An amorphous fluorine-containing polymer having a cyano group, an amidine group or an imidoylamidine group at the end of the main chain or side chain of the polymer. [Effect] The coating film of the fluoropolymer obtained by coating and heat-treating the fluoropolymer solution of the present invention, in particular, the coating film of the amorphous perfluoropolymer having an alicyclic structure is crosslinked, It has excellent mechanical properties at high temperature and is not easily deformed by external pressure. |
