Abstract: The invention relates to a process for the preparation of expanded polystyrene particles in which polystyrene beads containing water as the sole expanding agent are expanded. The process involves the following stages:A) the polystyrene beads are pre-expanded at temperatures above 100° C.,B) the pre-expanded particles are dried in dry air at temperatures between 20° and 95° C. over a period of from 1 to 10 hours,C) the dried expanded particles are further expanded with steam at temperatures ranging from 100° to 140° C., andD) the stages b and c are repeated as often as is necessary to achieve the desired bulk density.

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.

Abstract: The invention relates to a process for preparing styrene polymers comprising water as sole blowing agent, by polymerizing styrene in aqueous suspension. The polymerization is carried out in the presence of from 5 to 30% by weight of recycled EPS material dissolved in styrene and comprising customary coating agents deriving from production of the EPS.

Abstract: The invention relates to a method for producing styrene polymers containing water as the only inflating agent by polymerising styrene in an aqueous suspension in the presence of between 0.1 and 5 weight % of a thermolabile organic compound, which when the temperature is raised decomposes into amphiphilic and/or hydrophilic compounds, whereby the maximum polymerisation temperature is higher than the decomposition temperature of the thermolabile compound.

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.
