    Abstract: Described herein is a peroxide curable, partially fluorinated polymer derived from: (a) comonomers comprising: (i) 5-28 wt. % of tetrafluoroethylene; (ii) 30-70 wt. % of vinylidene fluoride; and (iii) a monomer selected from 10-45 wt. % of hexafluoropropylene and 10-40 wt, % of a perfluoro ether monomer of the formula Rf-0-(CF2)n—CF═CF2 wherein n is 1 or 0, and Rf represents a perfluoroalkyl residue which may or may not be interrupted by one or more than one oxygen atoms; (b) 0.01-2 wt % of a perfluorinated iodinated vinyl ether based on the total amount of comonomer, wherein the perfluorinated iodinated vinyl ether has the formula: F2C═CF—(CF2)m(0)o—(CF2)n—O—(CF2)p—I where m is 0 or 1; n is an integer of 0-5: o is 0 or 1: and p is an integer of 1-5, wherein when n is 0, o is 0; and (c) 0.01-2 wt % of a chain transfer agent based on the total amount of comonomers wherein the chain transfer agent consists of a diiodo-fluoroalkane and a diiodo-methane. Further described are methods of making the curable partially fluorinated polymers and articles comprising the cured fluoropolymer.
