Abstract
Disclosed are copolymers formed by copolymerization of: (1) one or more hydrofluoroolefin monomer(s) such as hydrofluoropropenes, (2) one or more of an alkyl vinyl ether monomer(s) that are not substituted with a reactive group, and (3) one or more reactive group substituted, lower alkyl vinyl ether monomer(s) wherein the copolymer has a MWn of from about 1000 to about 6000 grams/mole and other advantageous properties.
Claims10
A fluorocopolymer formed by copolymerization of:
- (1) one or more hydrofluoroolefin monomer(s) in an amount of from about 40 mole % to about 70 mole % based on all of the monomers in the copolymer
- (2) one or more of an alkyl vinyl ether monomer(s) that are not substituted with a reactive group in an amount of from about 20 mole % to about 40 mole % weight based on all of the monomers in the copolymer,
- (3) one or more reactive group substituted, lower alkyl vinyl ether monomer(s) in an amount of from about 5 mole % to about 20 mole % based on all of the monomers in the copolymer, and
- (4) optionally one or more of an alkyl vinyl ester monomer in an amount, when present, of not greater than about 20 mole % based on all of the monomers in the copolymer,
- wherein the copolymer has a MWn of from about 1000 to about 6000 grams/mole.
