Abstract: PURPOSE:To prepare a water selective and permeable separating membrane having such practical performances as superb separability, mechanical strength of membrane, etc. by utilizing photo-crosslinked photosensitive polyvinyl alcohol derivative to apply the porous high-molecular membrane. CONSTITUTION:The water solution of water soluble photosensitive resin such as polyvinyl alcohol or partial saponifiable vinyl acetate, etc. shown in the formula is applied on the porous high-molecular membrane such as cellulose acetate porous membrane, exposed to the interior light and the like after air-drying, sensitized and crosslinked with water soluble photosensitive resin to render the said membrane insoluble. By utilizing the composite membrane thus prepared, pervaporation is carried out to separate the water-ethanol mixing solution and the like.

Abstract: PURPOSE:To efficiently obtain methane gas, by using methane producing bacteria included and immobilized by a photosensitive polyvinyl alcohol prepolymer having a stilbazolium group in the side chain thereof. CONSTITUTION:Methane-producing bacteria included and immobilized by a photosensitive polyvinyl alcohol prepolymer having a stilbazolium group in the side chain thereof as a photosensitive group are used in org. waste water or org. waste. The introducing ratio of the stilbazolium group into the photosensitive polyvinyl alcohol prepolymer is pref. 1.0-7.0mol% to the mol number of the vinyl group is the prepolymer. From the aspect of the production of methane, it is effective and preferable that the polymerization degree of the polyvinyl alcohol component of the photosensitive polyvinyl alcohol prepolymer is 300-2,500 and the saponification degree thereof is 65-88%.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal cell using a tilt alignment film for a liquid crystal having high productivity in which any tilt angles can be designed, by irradiating a resin film containing a photoisomerization reaction structural unit with non-polarized light in an oblique direction. SOLUTION: A resin film containing a photoisomerization reaction structural unit is irradiated with non-polarized light in an oblique direction to form a tilt alignment film for a liquid crystal. The resin film used contains a photoisomerization reaction structural unit, and the photoisomerization reaction structural unit preferably has at least one double bond selected from N=N and C=C bonds and causes geometrical photoisomerization reaction by irradiation of light. As for the photoisomerization reaction structural unit having N=N bonds, for example, azobenzene and azopyridine can be used. As for the photoisomerization reaction structural unit having Cr=C bonds, for example, stilbene and stilbazole can be used. As for the resin containing the photoisomerization reaction structural unit, any of vinyl polymers, ring-opened polymers or the like can be used.

Abstract: PURPOSE:To obtain the subject sheet containing the bacterial cellulose of ribbon- like fibril form and excellent in dynamic characteristics such as expansion resistance and elasticity. CONSTITUTION:Acetobacter aceti xylinum ATCC 10821 bacteria as a microorganism for producing bacterial cellulose is cultured, and the gel-like film formed in the upper layer of the culture solution and containing a bacterial cellulose polysaccharide is disaggregated and subsequently filtered off to obtain the bacterial cellulose disaggregation product comprising ribbon-like fibrils. A wood pulp slurry is mixed with the produced bacterial cellulose disaggregation product and subsequently processed into a paper sheet. The paper sheet is impregnated with a composition containing a phenolic resin, dried with air, and subsequently heat-pressed to obtain a phenolic resin laminate board.
