Title
(EN) AQUEOUS FLUOROPOLYMER DISPERSIONS
(FR) DISPERSIONS AQUEUSES DE POLYMERES FLUORES
Abstract
(EN)
A stable, aqueous fluorocopolymer dispersion prepared by aqueous dispersion polymerization of: a) a dispersed phase containing a fluoroolefin monomer component and a vinyl ether monomer component in the presence of b) a base neutralized, stable aqueous dispersion of a polymeric dispersant having an acid value of at least 1.5 mg KOH/gram not exceeding about 35 mg KOH/gram and the amount of neutralizing base does not exceed about 10 % based on resin solids of the dispersant. The acid value is adapted to provide a stable dispersion of the fluorocopolymer in water without externally added surfactant. Thermoplastic and thermosetting coating compositions can be prepared from these aqueous fluorocopolymer dispersions.
(FR)
Dispersion stable, aqueuse, de copolymères fluorés préparée par polymérisation d'une dispersion aqueuse de: a) une phase dispersée contenant un constituant monomère de fluoro-oléfine et un constituant monomère de vinyl-éther en présence de b) une dispersion aqueuse stable, neutralisée par une base, d'un dispersant polymère d'indice d'acidité d'au moins 1,5 mg KOH/gramme et ne dépassant pas environ 35 mg KOH/gramme, la quantité de base neutralisante ne dépassant pas environ 10 % par rapport aux matières solides de résine du dispersant. L'indice d'acidité est adapté pour donner une dispersion stable du copolymère fluoré dans l'eau sans adjonction externe d'un tensioactif. Il est possible de préparer des compositions de revêtement thermoplastiques et thermodurcissables à partir de ces dispersions aqueuses de copolymères.
