Abstract
A fluorine containing polymer containing ester groups in the backbone of the polymer is prepared by the ring opening free radical polymerization of a cyclic ketene acetal with a vinyl monomer component comprising a fluorine containing vinyl monomer. The aforesaid fluorine containing polymer which contains ester groups can be reacted with a material containing functional groups capable of cleaving the carbon oxygen single bonds of the ester groups. The resultant oligomeric material contains functionality as a result of the cleavage which is suitable for reaction with a crosslinking agent to form a cured film.
