    摘要： To provide the method for concentrating an aqueous dispersion of fluorine-containing polymer particles containing a surfactant, which is applicable to a fluorine-containing polymer such as PTFE being easily fibrilated and assures low energy, low cost and short term concentration only by using various kinds of surfactants in a small amount. The method for concentrating an aqueous dispersion of fluorine-containing polymer particles containing the surfactant by feeding the aqueous dispersion of fluorine-containing polymer particles containing the surfactant in an amount of 2.0 to 8.0% by weight based on a solid content of the fluorine-containing polymer to a micro filtration membrane having a pore size of 0.01 to 1 .mu.m with aqueous dispersion feeding means which does not substantially generate shearing force and then removing an aqueous medium containing the surfactant from the aqueous dispersion.
