Abstract: PURPOSE:To obtain fine particulate polymer having an orderly particle diameter distribution, by charging a liquid chamber provided with a piezoelectric element with a monomer, increasing the pressure in this chamber by applying a pulsed voltage to the element, discharging a fine particulate monomer from a nozzle and polymerizing and curing the monomer. CONSTITUTION:The front end of a liquid chamber 20 communicating with a feed tank 10 is provided with a nozzle 21 having fine holes. Liquid chamber 20 is surrounded with a piezoelectric element 22. After liquid chamber 20 has been filled to its front end with a monomer or an oligomer fed from the feed tank 10, a pulsed voltage from a means 23 for applying a pulsed voltage is applied to piezoelectric element 22 to allow it to contract inwardly as shown by the broken lines and generate a pressure in liquid chamber 20. In this way, fine particulate monomer or oligomer is discharged from nozzle 21 and is received by a receiver 30 filled with a liquid in which the monomer or the oligomer is not soluble. This monomer or oligomer is polymerized and cured to obtain fine particulate polymer.

Abstract: PROBLEM TO BE SOLVED: To inexpensively attach a splash free organic compound to an opticalarticle by vacuum evaporation or the like by covering the surface of the organic compound directly or indirectly via a gap with a fibrous material and heating it under vacuum. SOLUTION: The surface of an organic compound, which is an evaporating source, is heated under vacuum being coated with a fibrous material either directly or indirectly via a gap. The organic substance is acceptable so far as it is comparatively stable to heat, has a property to evaporate under vacuum and is able to form a coating film on a surface of a substrate after vapor deposition. From the viewpoint of uses, it is especially preferable that the substance can be converted to a stain-proofing agent with a water- or oil-repellent function, or a low refractive index film as an antireflection film. The fibrous material is required to produce no or only a small amount of discharged gas by thermal decomposition at the evaporation temperature of the organic compound. Metallic fiber, ceramic fiber, glass fiber, rock wool, asbestos fiber, carbon fiber, polyimide fiber, aromatic polyamide fiber or the like can be mentioned as its example.
