Abstract: The invention relates to a process to produce a stable fluoropolymer latex using non-fluorinated surfactant with greater thermal stability. The polymerization is run at pressures greater than typically used. The resulting polymer exhibit improved melt color stability as compared to those produced under similar conditions at lower pressures.

Abstract: The invention relates to novel linear, semi-crystalline, functional fluoropolymers that have been obtained by copolymerizing a fluorinated vinylic monomer and a hydrophilic monomer chosen from vinyl alkyl acids, vinyl phosphonates, functional acrylamides, carbonates, vinyl ethers, alkoxy compounds, and double hydrophilic group monomers.
