<P>PROBLEM TO BE SOLVED: To provide a porous film and a sheet material of an alkyl vinyl ether/maleic anhydride copolymer in which the average pore diameter and porosity are suitably set. <P>SOLUTION: The film and sheet material are composed of the alkyl vinyl ether/maleic anhydride copolymer having 0.5-20 μm average pore diameter and 50-80% porosity according to a dry phase inversion method. Furthermore, the ratio of the thickness (T) of the film and sheet material to the average pore diameter (d) thereof is preferably ≥1 to ≤5. The material formed on a substrate composed of a fibrous material, paper, a nonwoven fabric, a granular material, a woven fabric, a filamentary material or a porous material is suitable as a deodorant/moisture absorbent composition. Furthermore, sanitary goods, anti-perspiration pads, diapers, caring articles and sanitary articles comprising the material as a part of formations are obtained. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
