    摘要: A thermoplastic resin film excellent in slipperiness, wear resistance and transparency contains 0.05 to 0.5 wt. % of specified fine particles of composite oxide comprising silica, alkali metal oxide, and at least one inorganic oxide other than silica, wherein the fine particles satisfies the following expression (I):S .gtoreq.10,000/(Dp*SG) (I)wherein S indicates the specific surface area (m.sup.2 /g) of the fine particles of composite oxide, Dp indicates the average diameter (nm) of the fine particles, and SG indicates the true specific gravity thereof. The film is preferably a polyester film having a hazing value of 5% or less. It is suitable for use as magnetic tape, capacitor, photographic film and pressure-sensitive adhesive tape. The film is manufactured by adding a silicate of alkali metals, ammonium or organic bases and an alkali-soluble inorganic compound simultaneously to an alkali solution with pH 9 or above, generating fine particles of composite oxide without any control of the pH of this reaction solution, adding the obtained sol to a thermoplastic resin and/or the reaction system thereof, and processing of a film.

    摘要: In a process for preparing spherical particles of a metal oxide or hydroxide having a particle size of from 0.1 to 10 .mu.m by adding a corresponding metal alkoxide to a dispersion of water-alcohol system having dispersed therein a metal oxide or hydroxide as a seed, under alkaline conditions and allowing a decomposition product from said metal alkoxide to attach onto said seed to effect particle growth of the seed, the improvement which comprises maintaining said dispersion at a substantially constant pH within the range between 10 and 13 during the addition of the metal alkoxide to said dispersion and the subsequent particle growth of the seed, thereby to prepare mono-dispersed particles substantially free from particle aggregation having a sharp particle size distribution of a standard deviation of not greater than 0.5. The white particles so prepared may be, after separation, heat treated to provide black particles. The white or black particles may be coated with a synthetic resin in the surface. The products are useful particularly as spacers for liquid crystal display devices.
