    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.

    Abstract: A composition includes an amorphous fluoropolymer having at least one of: a segment represented by formula I: —CF(Rf)—(CX2)n—(CX2CXR)m—O—R″fOk—(CXR′CX2)p—(CX2)q—CF(R′f)— (I); or a terminal segment represented by formula III: Rf—CF(I)—(CX2)n—(CX2CXR)m—O—R″fOk—(CXR′CX2)p—(CX2)q—CF(R′f)— (III), and fluoroplastic particles having a mean particle size of less than 500 nanometers. Each X is independently F, H, or Cl; Rf and R′f are each independently F or a monovalent perfluoroalkyl having 1 to 3 carbon atoms; R is F or a partially fluorinated or perfluorinated alkyl having 1 to 3 carbon atoms; R″f is a divalent fluoroalkylene having 1 to 8 carbon atoms or a divalent fluorinated alkylene ether having 1 to 20 carbon atoms and at least one ether linkage; k is 0 or 1; and n, m, p, and q are each independently an integer from 0 to 5, with the proviso that when k is 0, n+m is at least 1 and p+q is at least 1. A method of making the composition is also provided.
