Abstract
A monodispersed glycol suspension having excellent dispersion stability, including a monodispersed suspension in a glycol of spherical fine particles of an amorphous inorganic oxide having an average particle diameter of 0.05 to 5 micrometers and a relative particle size standard deviation of 1.0 to 1.5 and containing glycol bonded to its surface. This monodispersed suspension is useful as a raw material for the production of a polyester film having improved slipperiness.
