A process for producing a melamine-formaldehyde foam by heating and foaming an aqueous mixture M using microwave radiation, said mixture M comprising at least one melamine-formal-dehyde precondensate, at least one curative, at least one surfactant, at least one blowing agent and at least one linear polymer with a number average molecular weight Min the range from 500 to 10,000 g/mol and at least two functional groups selected from OH, NHor COOH as well as a melamine-formaldehyde foam obtainable by this process and its use.

Production of melamine-formaldehyde foams

The present invention relates to processes for producing melamine-formaldehyde foams, said processes comprising the steps of:

Method for producing melamine/formaldehyde foams

The present invention relates to melamine-formaldehyde foams comprising hollow microspheres wherein said hollow microspheres have a median particle diameter (D, volume averaged, Malvern, Fraunhofer diffraction) in the range from 260 &#x3bc;m to 490 &#x3bc;m, and also processes for producing these melamine-formaldehyde foams and their uses.

Melamine-formaldehyde foams comprising hollow microspheres

Melamine-formaldehyde foams comprise from 80% to 98% by weight of an inorganic filling material, wherein the % by weight are based on the total weight of inorganic filling material plus melamine-formaldehyde precondensate used for foam production.

Melamine resin foam with inorganic filling material

The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl-carboxamides, which are substantially salt-free and comprise anionic polymeric stabilizers having a comb-like molecular structure, processes for the preparation of the dispersions in the presence of anionic polymeric stabilizers having a comb-like molecular structure and the use of the dispersions as retention aids or fixing agents in papermaking.
