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： 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.

摘要： The present invention relates to cellulose esters having low hydroxyl content for use in optical applications, such as liquid crystal display (LCD) films. Films made with low hydroxyl levels and a given ratio of non-acetyl ester to hydroxyl level have been found to have low intrinsic birefringence. Therefore, these films can be cast, molded, or otherwise oriented without an appreciable birefringence or optical distortion (i.e. retardation). Such features make these films useful in polarizer, protective, and compensator films as well as molded optical parts, such as lenses. Furthermore, it has also been found that resins of the present invention can also be made to have +C plate behavior either by melt or solvent based processing, a characteristic which is not typical of cellulose esters. Such +C behavior allows films to be produced having unique compensatory behavior. Other embodiments of the invention relate to methods melt casting films while minimizing birefringence formation. Another embodiment of the invention is directed to films made from the cellulose esters described herein further comprising a plasticizer.
