摘要 |
An aqueous dispersion comprising an aqueous medium and colloidal particles of a fluorine-containing copolymer having an average particle size of about 0.05 to 1.0 um dispersed therein, each colloidal particle being constructed with a core portion made of a polymer comprising about 99 to 100% by weight of units of tetrafluoroethylene and about 0 to 1% by weight of units of at least one other fluoroolefin and a shell portion made of a polymer comprising about 50 to 97% by weight of units of tetrafluoroethylene and about 3 to 50% by weight of units of chlorotrifluoroethylene, the amount of chlorotrifluoroethylene in the core and shell portions being from about 2.5 to 25% by weight based on the entire amount of the core and shell portions.
