Abstract: Polystyrene foam particles having a density of 10 to 30 kg/m are obtained when styrene polymers containing 0.7 to 3 mol/kg of a blowing agent mixture comprising 60 to 90 mol% of water and 10 to 40 mol% of a C4- to C5-hydrocarbon are foamed using microwaves.

Abstract: Bead-form expandable moulding compositions of high heat resistance contain from 80 to 99 % by weight of a styrene polymer, from 1 to 20 % by weight of poly(2,6-dimethyl)-1,4-diphenyl ether, from 3 to 10 % by weight of a C3-C6-hydrocarbon as blowing agent and optionally conventional additives. They are obtained by suspension polymerisation of a solution of the polyphenylene ether in styrene.

Abstract: 1. A binder for building adhesives, troweling mixes and plasters which is based on a halogen-free emulsion copolymer of monoolefinically unsaturated carboxylates, wherein the emulsion copolymer comprises (a) from 55 to 72 % by weight of vinyl propionate, (b) from 44,9 to 27,5 % by weight of tert.-butyl acrylate, (c) from 0.1 to 0.5 % by weight of acrylic acid or methacrylic acid, and (d) from 0 to 17.5 % by weight of a monoolefinically unsaturated carboxylate from the group comprising vinyl acetate, methyl acrylate and methacrylate, n- and isobutyl acrylate and methacrylate and dibutyl maleate, the percentages being based on the total amount of the monomers.
