    Abstract: A system is described for producing an in-situ PUR foam, consisting of the components • 50 to 98 percent by weight of one or more inorganic fillers A), • 1 to 48 percent by weight of one or more water-soluble, cationic polymers B) • 0.5 to 48 percent by weight of one or more surfactants C) • 0.01 to 5 percent by weight of one or more cross-linkers D) which are reactive with the polymers B), • 0 to 20 percent by weight of one or more additives E), wherein the weight percentages of components A) to E) relate to the non-aqueous proportions and the total of A) to E) is 100 percent by weight. The inventino further relates to a method for producing an in-situ PUR foam using the components of the system and foaming with a gas or a gas mixture, and to a use for thermally insulating and filling-in cavities and hollow articles.

    Abstract: Thermoplastic molding compositions, comprising E) from 10 to 99.9% by weight of a thermoplastic polymer, F) from 0.01 to 10% by weight of a copolymer obtainable via free-radical-initiated aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one dispersing agent and of at least one free-radical initiator by the feed process, where the emulsion polymerization uses from 70 to 99.5% by weight of alpha,beta-monoethylenically unsaturated compounds [monomers A], and from 0.5 to 30% by weight of compounds having at least two ethylenically unsaturated groups capable of free-radical copolymerization [monomers B], and also, if appropriate, up to 5% by weight of alpha,beta-monoethylenically unsaturated mono- or dicarboxylic acids having from 3 to 6 carbon atoms and/or their amides [monomers C], where the monomers A to C give a total of 100% by weight (entire amount of monomers) and the monomer feeds take place in such a way that >=60% by weight of the entire amount of monomers B are fed to the polymerization mixture under polymerization conditions at a juncture after >=60% by weight of the entire amount of monomer have been fed to the polymerization mixture under polymerization conditions, from 0 to 70% by weight of further additives, where the total of the percentages by weight of components A) to C) gives 100%.
