Abstract
Official abstract text for this publication.
Fluoropolymers containing one or more azide group wherein the azide group is not a sulfonyl-azide group and processes of preparing them.
First claim
Opening claim text (preview).
What is claimed is: 1 . A curable composition comprising: (a) a fluoropolymer containing one or more azide groups wherein the azide group is not a sulfonyl-azide group; and (b) a curing agent, wherein the curing agent comprises at least one a carbon triple, and wherein the curable composition is substantially free of a metal catalyst. 2 . The curable composition according to claim 1 , wherein the fluoropolymer is derived from one or more fluorinated monomers selected from at least one of: tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride. 3 . The curable composition according to claim 1 , wherein the fluoropolymer is derived from fluorinated vinyl ethers. 4 . The curable composition according to claim 1 , wherein the fluoropolymer is derived from one or more fluorinated monomers in combination with ethylene, propylene or ethylene and propylene. 5 . The curable composition according to claim 1 , wherein the fluoropolymer comprises repeating units derived from the monomers selected from vinyl fluoride, vinylidene fluoride, and a combination thereof. 6 . The curable composition according to claim 1 , wherein the fluoropolymer is partially fluorinated. 7 . The curable composition according to claim 1 , wherein the fluoropolymer is perfluorinated. 8 . The curable composition according to claim 1 , wherein the azide group corresponds to the formula —CX1X2N 3 , wherein X1 and X2 represent independently from each other H or F. 9 . The curable composition according to claim 1 , wherein the azide group corresponds to the formula —[C(X1)(X2)] m -C(Y1)(Y2)N 3 , wherein X1, X2, Y1, and Y2 represent, independently from each other, F or H and m represents 0 or 1. 10 . The curable composition according to claim 1 , wherein the curing agent is an alkyne or alkyne derivative.
