Abstract
Official abstract text for this publication.
The present invention provides 1,3,3,3-tetrafluoropropene (HFO-1234ze) copolymers comprising 1,3,3,3-tetrafluoropropene and one or more comonomers selected from the group consisting of vinyl fluoride (VF), vinylidene fluoride (VF 2 ), tetrafluoroethylene (TFE), chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), and perfluoro(alkyl vinyl ether) (PAVE), wherein said alkyl contains 1 to 5 carbon atoms, the copolymers being a fluoroplastic or a fluoroelastomer, depending upon monomer content.
First claim
Opening claim text (preview).
What is claimed is: 1. A copolymer comprising 1 to 40 mol % 1,3,3,3 tetrafluoropropene, 15 to 60 mol % vinylidene fluoride, 5 to 25 mol % tetrafluoroethyene, and 15 to 40 mol % perfluoro(alkyl vinyl ether), to total 100 mol %. 2. The copolymer of claim 1 wherein said perfluoro(alkyl vinyl ether) is perfluoro(methyl vinyl ether). 3. The copolymer of claim 1 wherein said copolymer is a fluoroelastomer.
