Abstract:
The invention relates to a method for the production of water absorbent polymer particles by polymerizing drops, comprising at least one monomer in a gas phase surrounding the drops, wherein the drops are produced by surrounding a first monomer solution with a second monomer solution and polymerizing the second monomer solution to a higher cross-linked polymer than the first monomer solution.
Abstract:
The invention relates to fire extinguishing and/or fire-retardant compositions, containing at least one water-absorbing polymer and at least one alkaline salt of a non-polymeric saturated carboxylic acid, to a method for the production thereof and to the use of these compositions for fighting fires or as fire-retardant coatings.
Abstract:
The invention relates to highly functional polyether polyols of general formula (I), where R'1 = an unsubstituted or substituted aliphatic or aromatic group, R'2 = an unsubstituted or substituted aliphatic or aromatic group, H, OH, polyalkylether chains or halogen, X = polyalkylether chains or H, where at least one X = a polyalkylether chain, m = a whole number from 0 to 20, where if m = 0, then Xm = H and n = whole numbers from 4 to 12. The invention further relates to methods for production of said highly functional polyether polyols and the use thereof for the production of polyurethanes and non-ionogenic detergents.
Abstract:

Abstract:
Use of aqueous dispersions of water-soluble and/or water-swellable anionic polymers and water-soluble neutralizing agents as an additive to aqueous extinguishing agents, and method for fighting fires with aqueous extinguishing agents, an aqueous dispersion of water-soluble and/or water-swellable anionic polymers and at least one water-soluble neutralizing agent being mixed with water so that the mixture has a polymer content of not more than 5% by weight and a pH of at least 5.5.
Abstract:
A fire extinguishing and/or retardant composition, contains at least one water absorbing polymer and at least one alkaline salt of a non-polymeric saturated carboxylic acid. The composition also contains water, and a foaming agent.
Abstract:
The invention concerns water-absorbing polymers for producing fire-retarding compositions, comprising at least one interpolymerized ethylenically unsaturated monomer bearing acid groups, wherein from 51 to 64 mol % of the acid groups are present as carboxylate groups and some or all of the carboxylate groups have potassium ions as counterions, processes for producing the water-absorbing polymers and also the production of fire-retarding compositions and coatings.
