    摘要： The present invention provides a method for producing resin beads which can provide various types of products, such as cosmetics, imparted with superior tactile impression, spreadability on the skin, transparency, and product stability, and which can be substituted for resin particles composed of a synthetic material derived from petroleum. The method is a method for producing resin beads containing a cellulose derivative as a main component. The production method includes: a suspension preparation step of mixing an oil phase containing the cellulose derivative and an organic solvent that dissolves the cellulose derivative, the organic solvent having a water-solubility of 0.1 to 50.0 g, and an aqueous phase containing a dispersion stabilizer, thereby preparing a suspension containing oil droplets containing the cellulose derivative and the organic solvent; and an oil droplet contraction step of adding water to the suspension, thereby contracting the oil droplets, wherein the water is added to the suspension in such a way as to satisfy the following expression (A) until a content of the organic solvent in the suspension becomes equal to or less than the water-solubility of the organic solvent. W/S / T ≤ 1 .00 wherein
    W: an addition amount of water (parts by mass),
    S: an amount of the suspension (parts by mass), and
    T: a time (minutes) required for addition.

    摘要： A method of coating hydroxylated surfaces by gas phase grafting is described. Especially acyl groups, silyl groups and/or alkyl groups are located on the surface of materials by gas phase grafting. The grafting method is a dry process. The material to coat can be organic or inorganic materials. The produced surface coated material are strong and durable and material normally not water-proof can be water-proof due to the surface treating. Examples of items produced from surface treated material may be water-proof cardboard boxes, other containers, furniture, interior for cars and boats. Items produced from organic materials such as from plant parts are biodegradable.

    摘要： The invention relates to a polymer material with several advantageous properties. The polymer material has a low degree of swelling in water, it is biodegradable, it has extremely low permeability to gasses such as CO
    2 and it has a high strength. The polymer material is useful for a number of purposes, such as for preparing containers for food or beverages. The polymer material is prepared from a prepolymerisation mixture comprising grafted plant derived material and monomers and/or cross-linkers.

    摘要： Modified fine cellulose fibers are produced by impregnating a cellulose with a reactive fibrillation solution or mixture containing a catalyst including a base catalyst or an organic acid catalyst, a monobasic carboxylic anhydride, and an aprotic solvent having a donor number of not less than 26 to esterify and chemically fibrillate the cellulose. This method provides a simple efficient process for producing modified fine cellulose fibers that have a diameter from several nano-meters to submicrometers, a large aspect ratio, a high degree of crystallinity, less damage in the shape or crystalline structure of the fine fibers, a large aspect ratio, and an excellent dispersibility in an organic solvent; The catalyst may contain a pyridine compound. The monobasic carboxylic anhydride may be a C 2-4 aliphatic monocarboxylic anhydride. The resulting modified fine cellulose fibers modified with a monobasic carboxylic anhydride may have a degree of crystallinity of not less than 70%, an average fiber diameter of 20 to 800 nm, and an average fiber length of 1 to 200 µm.
