Abstract
The present invention pertains to durable, chemically-resistant films made from terpolymers. These terpolymers include repeating units of a fluorinated unsaturated monomer, a diester of an unsaturated anhydride with at least one hydroxyl group, and an olefin. The novel films result from curing a coating composition which include: (a) a polymeric component which includes the terpolymers described above, and (b) a crosslinking component. The films of the present invention have many of the excellent physical properties typically associated with those derived from hydroxy-functional fluoropolymers.
