Abstract
This invention describes the preparation and characterization of cross-linkable fluoropolymers, These cross-linkable fluoropolymers contain keto functional monomer. The keto functional monomer is incorporated on fluoropolymer while crosslinking agent was post-added after polymerization. The cross-linking reaction occurs after water/solvent evaporation or during melt processing.
