To inexpensively produce the subject polymer excellent in crosslinking properties and adhesiveness by grafting a fluorine-containing polymer with a specific organosilicon compound.
This grafted fluorine-containing polymer is obtained by melting and kneading (A) a fluorine containing polymer having H atom binding to C atom of a main chain with (B) an organosilicon compound represented by formula I or formula II {one or two group of R1 to R3 and R7 to R9 are each a silylalkyl group of formula III [R6 is an alkylene; R4 and R5 are each a (substituted)monofunctional hydrocarbon; (n) is 1-3] and the residue is a monofunctional organic group having an unsaturated bond} and (C) a radical generator at a temperature at which the component C generates radical.
