Abstract: The invention relates to expandable polystyrene particles which contain foaming agents and are coated with 0.01 to 0.5 wt. % of a waterproofing agent which melts above 10 ~C and has an average particle size of less than 100 .mu.m. The particles are processed to form moulded foam structures with a reduced water absorption capacity.

Abstract: The invention concerns a method of producing expandable styrene-polymer spheres by polymerizing styrene, optionally using other comonomers, in aqueous suspension in the presence of organic-molecule colloids as suspension stabilizers and the usual styrene-soluble polymerization catalysts, and with the addition of a propellant and optionally other additives in effective amounts, the aqueous suspension containing at least one olefinically unsaturated carboxylic acid, or a water-soluble salt thereof, present in a amount, relative to the organic compounds present, of 0.002 to 0.3 % by wt. of carboxylic-acid anions.

Abstract: Expandable styrene polymers of high expandability comprise a) a styrene polymer having a viscosity, measured in toluene, of from 55 to 80 [ml/g] and a melt flow index MFI (190 DEG C., 3.8 kp) of from 7.5 to 30 [g/10 min], b) from 1 to 10% by weight, based on a), of a C3- to C6-hydrocarbon as blowing agent, and, if desired, c) conventional assistants in effective amounts.
