Abstract

Process for the manufacture of solid, open-pored bodies based on plastic materials, in which a water-in-oil emulsion is cured, which contains in the continuous phase a polymerizable liquid, with at least one monomeric compound with one group (see formula) terminal, characterized in that: a) from 20 to 60 parts by weight of water are mixed; b) of (see formula) a (see formula) parts by weight of a polymer or copolymer in powder form, insoluble in water, which is at least swellable in c); c) 100- (a +) parts by weight of at least one water-emulsifiable, liquid polymerizable monomer with one group (see formula) terminals; d) water soluble wetting agents that can either be added at the beginning or can be contained in step b), as produced; e) small amounts of surfactants with non-ionogenic activity in the boundary layer as water-in-oil emulsifiers, especially polyoxypropylene glycols of general formula HO (C2H4O) a (C3H6O) b) (C2H4O) CH, which are obtained by polymerization of propylene oxide and reaction with ethylene oxide and whose hydrophobic residue has a molecular weight of at least approximately 2500 and whose global molecule contains from 20 to 70% of hydrophilic groups, and f) one or more polymerization catalysts and/or accelerators, especially redox systems.
