Abstract: A method for modifying fibers is provided, which method comprises dispersing in water or a dilute alkali aqueous solution under shear a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydoxyalkyl group ranges from 0.05 to 1.3, applying the resulting dispersion to fibers, and drying the applied fibers.

Abstract: A method for modifying fibers is provided, which method comprises suspending and dispersing in water under shear force a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydroxyalkyl group ranges from 0.05 to 1.3, applying the resulting dispersion and a crosslinking agent or an aqueous resin emulsion to fibers, and thermally treating the applied fibers.

Abstract: Fibers are modified by applying a solution of a low substituted cellulose ether having a molar degree of substitution with alkyl and/or hydroxyalkyl groups in the range of 0.05 to 1.0 in an aqueous alkali solution to fibers, and causing the solution borne on fibers to coagulate. The method achieves satisfactory fiber modifications with respect to antistatic property, moisture absorption and shrink resistance without a cumbersome step of dissolution while ensuring safety.

Abstract: In a paper/film composite structure, the film is made of a low substituted cellulose ether having a molar degree of substitution with alkyl and/or hydroxyalkyl groups in the range of 0.05 to 1.3. The paper/film composite structure can be delivered to the waste paper recycling process without previously removing the film portion. The strength of film is increased without adding to the manufacturing cost. The paper/film composite structure is inexpensive and eliminates the risk of film rupture during the working, transporting and use stages.

Abstract: Proposed is a novel and very efficient method for the preparation of an N-vinyl compound such as N-vinyl-2-pyrrolidone and N-vinyl-N-ethyl acetamide by the thermal decomposition of an N-(.alpha.-acyloxyethyl) compound which is a novel compound obtained by the addition reaction between an NH group-containing compound such as 2-pyrrolidone and N-ethyl acetamide and a vinyl carboxylate, e.g., vinyl acetate, in the presence of an alkali, e.g. alkali metal hydroxide. The reaction mixture after completion of this addition reaction as such, i.e. without isolating the N-(.alpha.-acyloxyethyl) compound, such as N-(.alpha.-acetoxyethyl)-2-pyrrolidone and N-(.alpha.-acetoxyethyl)-N-ethyl acetamide, is heated to effect in situ formation of the desired N-vinyl compound which can then be isolated by distillation under reduced pressure in a very high overall yield.

Abstract: Proposed are an N-(.alpha.-acyloxyethyl) compound, e.g., (N-(.alpha.-acetoxyethyl)-2-pyrrolidone, which is a novel compound and can be converted into an industrially very important N-vinyl compound, e.g., N-vinyl-2-pyrrolidone, by a thermal decomposition reaction under relatively mild conditions as well as a method for the preparation of such an N-(.alpha.-acyloxyethyl) compound. The N-(.alpha.-acyloxyethyl) compound can be synthesized in a high yield by the addition reaction of an NH group-containing compound, e.g., 2-pyrrolidone, with a vinyl carboxylate, e.g., vinyl acetate, in the presence of an alkaline compound such as alkali metal hydroxides.

Abstract: The invention discloses a novel modified polyvinyl butyral polymer having photocurability and heat-curability containing an ethylenically unsaturated moiety, which is introduced by the reaction of, for example, N-methylol acrylamide with a part of the hydroxyl groups, in addition to the vinyl butyral moiety, vinyl acetate moiety and vinyl alcohol moiety constituting conventional polyvinyl butyral resins. The inventive polymer is useful for various types of adhesives, coating materials, interlayers of laminated shatter-proof glass and the like similarly to unmodified polyvinyl butyral resins but with a possibility of broadened utilizability and absence of the problems due to evaporation of organic solvents.
