    摘要： This invention relates to an aqueous dispersion of (a) from 0.5 to 99.5 weight percent of a fluoropolymer having an average particle size of from 0.01 to 30 microns; and (b) from 0.5 to 99.5 weight percent of an ethylene copolymer which comprises at least 50% by weight ethylene, 1-35% by weight of an acid-containing unsaturated mono-carboxylic acid, and optionally 0-49% by weight of a moiety selected from at least one of alkyl acrylate, alkyl methacrylate, vinyl ether, carbon monoxide and sulfur dioxide, and further wherein the acid groups are neutralized from 0-100% by a metal ion or other cations, the weight percents being based on the total amounts of (a) and (b) only. The invention also relates to a coprecipate of this aqueous dispersion and a dry powder made by drying the aqueous dispersion or coprecipitate.
