    • A process for producing a silane-modified cationized polymeric compound, the process including the steps of: (1) cationizing a water-soluble polymeric compound in a mixed solvent of a water-miscible organic solvent and water in the presence of an alkali to produce a slurry containing a cationized polymeric compound, (2) adding an aminosilane compound to the slurry or a cake produced therefrom, thereby treating the cationized polymeric compound with the aminosilane compound, (3) optionally adding an acid to the slurry obtained in step (1) or a product obtained in step (2), and (4) drying a product obtained in step (2) or a product obtained by performing step (3) after step (2), wherein the drying step (4) includes a primary drying treatment step of performing drying at a temperature of 50 to 140° C. under a degree of vacuum of 4.0 to 53.3 kPa, and a secondary drying treatment step of drying the product obtained following the primary drying treatment at a temperature of 90 to 155° C. The process enables a silane-modified cationized polymeric compound having excellent water dispersibility to be produced with good efficiency.

    • An elastic laminate sheet comprising a laminate comprising an elastomer layer and a nonwoven fabric provided on at least one surface of the elastomer layer, wherein low elastic laminate part and high elastic laminate part are alternatingly provided in one direction to form the laminate, and the low elastic laminate part and the high elastic laminate part both have a first bonding region where the elastomer layer and the nonwoven fabric are bonded and a second bonding region where the elastomer and the nonwoven fabric are bonded more weakly than at the first bonding region, and a total surface area of the first bonding region in the low elastic laminate part is larger than a total surface area of the first bonding region in the high elastic laminate part, and a ratio of an elastic modulus of the low elastic laminate part to an elastic modulus of the high elastic laminate part is more than 1 and not more than 7.5. The elastic laminate sheet does not easily break even when repeatedly stretched and demonstrates sufficient retention capacity for practical use even when attached to a main body part of a hygienic article or the like.
