Hydrolyzable silyl group-containing fluoropolymer preparation and hydrolyzable silyl group-containing fluoropolymer-containing composition

The present invention is excellent in storage stability, and to provide a method for producing a hydrolyzable silyl group-containing fluoropolymer having a sufficient pot life. Relative to the hydroxyl group of the hydroxyl group-containing fluoropolymer, is reacted with the isocyanate groups of the alkoxysilane having an isocyanate group when producing the hydrolyzable silyl group-containing fluoropolymer, a compound containing a specific metal atom carrying out the reaction by constant and concentration present.
