Abstract:
A process for producing coated foam beads, wherein an aqueous polymer dispersion is applied to the foam beads and then dried to form a water-insoluble polymer film, and foam moldings produced therefrom and the use thereof.
Abstract:
A process for production of expandable styrene polymers with narrow bead-size distribution with high specific reactor yield via polymerization of the monomers in aqueous suspension in a stirred tank in the presence of a volatile blowing agent, where the styrene-containing organic phase is added simultaneously with the aqueous phase to the stirred tank over a period of from 5 to 60 minutes.
Abstract:
The invention relates to a method for producing cellular material moulded articles from prefoamed cellular material polymer-coated particles in a pressurised mould, wherein said prefoamed cellular material particles comprise a filler, whose content ranges from 10 to 70 % by weight with respect thereto, and cellular material articles mould according the inventive method and the use thereof are also disclosed.
