Abstract
The present invention has an object to provide a process for producing a hydrolyzable silyl group-containing fluoropolymer which is excellent in storage stability and has a sufficient pot life. At the time of producing a hydrolyzable silyl group-containing fluoropolymer by reacting an isocyanate group of an isocyanate group-containing alkoxysilane to a hydroxy group of a hydroxy group-containing fluoropolymer, the reaction is carried out in the presence a compound containing a specific metal atom at a certain concentration.
