Claims20
A fluoropolymer composition comprising a copolymer comprising 39.5-57.0 mol % TFE, 42.0-57.5 mol % VDF and 1.0-3.0 mol % fluorinated ether, wherein the composition is melt processable.
A method of synthesizing a melt-processable fluoropolymer composition comprising the steps of providing TFE monomer, VDF monomer and fluorinated vinyl ether monomer, initiating the polymerization in the presence of a chain transfer agent, wherein the amount of CTA is from 0.01-0.5 mol % based on the total moles of monomer used in the polymerization process, said fluoropolymer composition comprising 39.5-57 mol % TFE, 42-57.5 mol % VDF and 1-3 mol % fluorinated vinyl ether.
