Abstract: A process for producing vinyl fluoride polymer comprising polymerizing vinyl fluoride in an aqueous polymerization medium containing initiator and halogen-free surfactant with a critical micelle concentration of less than about 0.05 weight percent at 25° C. The halogen-free surfactant is present in the aqueous polymerization medium in an amount less than about 0.1 weight percent based on the weight of the aqueous polymerization medium. The aqueous polymerization medium is essentially free of halogen-containing surfactant.An aqueous dispersion comprising vinyl fluoride polymer particles present in a range of from about 5 to about 40 weight percent based on the weight of the aqueous phase, wherein said vinyl fluoride polymer particles have a Dv(50) of less than about 20 microns, and halogen-free surfactant, wherein said halogen-free surfactant is present in said aqueous dispersion in an amount less than 0.1 weight percent based on the weight of the aqueous phase.

Abstract: A one or two layer coating system has been developed for plastic substrates. The one coating system low reflective layer consists of a fluorinated copolymer having the formula: VF2/TFE/HFP, VF2/HFP or VF2/TFE/PMVE. In the two coating system, the upper coating layer consists of TFE/HFP, VF2/TFE/HFP, or TFE/Perfluorodioxole, and the lower coating layer consists of VF2/TFE/HFP, VF/TFE/HFP, VAc/TFE/HFIB, or TFE graft to PVOH.
