Abstract: The invention relates to aqueous polymer dispersions which comprise an emulsion polymer of at least one .alpha.,.beta.-ethylenically unsaturated monomer M and at least one highly branched polycarbonate which is a hyperbranched polycarbonate having a degree of branching of 10% to 95%. The invention also relates to a process for preparing an aqueous polymer dispersion Pd by free-radical emulsion polymerization of at least one monomer M, where at least one highly branched polycarbonate is added before and/or during and/or after the emulsion polymerization. Additionally provided by the invention are methods of modifying the performance properties of an aqueous polymer dispersion Pd, and also the use of at least one aqueous polymer dispersion Pd as a binder in coating materials and paper coating slips.

Abstract: The process comprises filling a mold with a mixture containing cement, water and expandable styrene polymer granulates and then solidifying by heating at 80-250[deg] C under foaming of styrene polymer granulates. The heating is controlled so that the lightweight concrete has a density of 100-600 kg/m 3>. The heating of the mixture is carried out over a heatable form. The water used to produce the mixture is preheated at 30-90[deg] C.
