Abstract: A polyvinyl alcohol obtained by hydrolysis of a polyvinyl ester that contains silyl group functionalized monomer units.

Abstract: Provided are a leather-like sheet fabricated by infiltrating an aqueous resin dispersion (A) into a fibrous substrate, which satisfies a requirement (I) that the aqueous resin dispersion, (A) comprises essentially a main resin (a) stabilized with a surfactant, a polymer (b) having a polyoxyethylene group in its side chains, and a surfactant (c), a requirement (II) that the main resin (a) comprises an urethane resin (a1) and/or an urethane-acrylic composite resin (a2), and the resin skeleton contains from 1 to 10 mmols of a carboxyl group per 100 g of the resin, a requirement (III) that the polymer (b) is obtained through polymerization of a polyoxyethylene group-having ethylenic unsaturated monomer (b1) and any other ethylenic unsaturated monomer (b2) in a ratio by mass (b1)/(b2)=60/40 to 100/0, and a requirement (IV) that the percentage, % by mass (&agr;) of the polyoxyethylene group in the polymer (b) and the number of mols (&bgr;) of the amino group per gram of the polymer (b) satisfy 35≦&agr;&pl

Abstract: A polyvinyl alcohol having hydrolyzed silyl group functionalized monomer units.

Abstract: Cyclohexanetriol derivatives represented by the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different, and each denotes a hydrogen atom or a protecting group of a hydroxyl group,X denotes an oxygen atom, .dbd.CHCH.sub.2 OR.sup.4, .dbd.CHCHO or .dbd.CHCO.sub.2 R.sup.5, Y denotes a hydrogen atom and Z denotes --OR.sup.6, or Y and Z together form a single bond; or X and Z together form .dbd.NO--, .dbd.CHCH(OR.sup.7)O-- or .dbd.CHCO.sub.2 -- and Y is a hydrogen atom, R.sup.4 and R.sup.6 denote a hydrogen atom or a protecting group of a hydroxyl group respectively, R.sup.5 denotes a lower alkyl group, and R.sup.7 denotes a hydrogen atom or a lower alkyl group.Said derivatives are useful as synthetic intermediates of 1-hydroxyvitamin D derivatives.

Abstract: The solubility and evaporation rates of volatile fragrances, such as perfumes, in aqueous media, are improved by 3-methyl-3-methoxy butanol or an ester thereof. Homogeneous and clear aqueous solutions of as much as 20 to 30% fragrance can be achieved without incorporation of any surfactant. The aqueous fragrance solutions may be incorporated in wick type air freshener devices, which may be fan assisted.
