Abstract: The invention concerns a continuous process for preparing expandible styrene polymers by polymerizing styrene in the presence of expanding agents in three stages: a) preparing a solution of polystyrene in styrene; b) dispersing the solution in an aqueous phase; and c) continuously polymerizing out the prepolymer in an aqueous suspension.

Abstract: A process is disclosed for continuously producing expandable styrene polymers by polymerising styrene in the presence of expanding agents in three steps: (a) prepolymerising styrene in the mass; (b) dispersing the prepolymer in an aqueous phase; and (c) polymerising the prepolymer in an aqueous suspension.

Abstract: Process for production of foam webs or foam sheets, these webs or sheets being based on a polymer selected from polysulfones, polyetherimides, polyether ketones, and styrene polymers, via extrusion of a melt which comprises the polymer and a blowing agent, and then foaming of this melt, which comprises a process in which the melt also comprises from 1 to 50% by weight, based on the polymer, of a filler selected from A) a fibrous filler A, B) a particulate, non-graphite filler B, and mixtures of these.

Abstract: Water, or a mixture (pts. wt.) of water (100) and organic liquid (at most 200) is used as the blowing agent in a method for the production of foam sheet by extruding a mixture of polysulfone or polyethersulfone and volatile blowing agent (1-10 wt.%) under pressure at above 300 degreesC into the open air.
