A composition for dust-preventive treatment including an aqueous
dispersion of fluorine-containing polymer showing a low potential for
environmental concerns and a dust prevention effect as high as that of
known composition for dust-preventive treatment. The composition for
dust-preventive treatment includes an aqueous dispersion of
fluorine-containing polymer containing 50 ppm or less of a
fluorine-containing emulsifier. The composition for dust-preventive
treatment comprising aqueous dispersion of fluorine-containing polymer
containing 50 ppm or less of a fluorine-containing emulsifier can
preferably be obtained by removing the fluorine-containing emulsifier
from a polymer dispersion prepared by polymerizing tetrafluoroethylene
using the fluorine-containing emulsifier.
