    摘要： Disclosed is a method for determining the swellability and the swelling kinetics of superabsorbent material (9) such as polymer gels, for example, which comprises introducing a defined volume of the dry superabsorbent material (9) into a measuring vessel (7), using a movable element (4) within said measuring vessel (7) to apply a restraining force (12) to said superabsorbent material (9) and capturing the expansion of said superabsorbent material (9) contactlessly within a chamber (14) in a continuous manner by capturing the change in height of a piston (4) which bounds said chamber (14), travels in a measuring vessel (7) and is marked with a height scale (6).

    摘要： Hydrophilic open-celled resilient foams containing melamine-formaldehyde resins, characterized by a droplet absorption rate of less than 5 seconds and an EU standard EN ISO 14184-1 formaldehyde emission of less than 100 mg of formaldehyde/kg of foam, and obtainable by (a) heating an aqueous solution or dispersion each containing at least a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a curing agent to form a foam and crosslink the precondensate, (b) then conditioning the foam at from 120 to 300° C. for from 1 to 180 minutes to remove volatiles, and (c) treating the foam during the conditioning or thereafter with at least one hydrophilicizer and/or with ozone, a corona discharge or a plasma, are useful in hygiene articles to acquire, distribute and immobilize body fluids.
