    摘要： N,N',N"-tris-(2-hydroxyethyl)-melamine, if required, as a mixture with N-mono- and N,N'-bis-(2-hydroxyethyl)-melamine, is prepared by reacting melamine with ethanolamine in the presence of an acidic catalyst by a method in which the reaction is carried out at from 120.degree. to 250.degree. C. using an excess of ethanolamine, and the molar ratio of free ethanolamine to the sum of free and converted melamine is not permitted to fall below 4:1 during the entire reaction time, and the stated (2-hydroxyethyl)-melamines are used as modifiers in the prepartion of aminoplast resins which are suitable for laminating surfaces.

    摘要： Hydrophilic open-celled resilient foams comprising melamine-formaldehyde resins, obtainable by (a) heating and crosslinking 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, (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 polymer containing primary and/or secondary amino groups and having a molar mass of not less than 300, are useful in hygiene articles to acquire, distribute and immobilize body fluids.
