Abstract
Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.
Claims16
A copolymer of a) at least one halogenated olefin represented by the formula
- CX1X2═CX3X4
- wherein the halogenated olefin comprises at least one halogen atom and X1, X2, X3 and X4 are independently selected from a hydrogen atom, a chlorine atom, a fluorine atom, or a halogenated or non-halogenated alkyl group having 1 to 8 carbon atoms, and b) at least one halogenated alkenyl ethers represented by the formula
- CX5X6═CX7—OR1
- wherein X5, X6 and X7 are independently selected from a hydrogen atom, a chlorine atom, a fluorine atom, or a halogenated or non-halogenated alkyl group having 1 to 8 carbon atoms and at least one of X5, X6 and X7 is halogen or fluoralkyl and at least one of X5, X6 and X7 is hydrogen, and R1 is a non-halogenated alkyl group having 1 to 8 carbon atoms and substituted by at least one hydroxyl group, which may optionally contain one or more functional groups selected from carbonyl or ether functional groups and which may be substituted or unsubstituted wherein said halogenated alkenyl ether comprise at least one halogenated hydroxy alkenyl ether.
