Abstract: A process for the preparation of expandable styrene polymers having a molecular weight Mw of greater than 170,000 g/mol, which comprises conveying a blowing agent-containing styrene polymer melt having a temperature of at least 120° C. through a die plate with holes whose diameter at the die exit is at most 1.5 mm, and subsequently granulating the extrudate, and expandable styrene polymers (EPS) having a molecular weight Mw of more than 170,000 g/mol with 0.05 to 1.5% by weight of internal water.

Abstract: The invention relates to a method for the production of flameproof, expandable styrol polymers (EPS) by extruding a styrol polymer melt containing a propellant and flameproof agents through a nozzle plate with subsequent under water granulation. The residence time of the flameproof agent is less than 30 minutes at a melting temperature in the region of between 140 to 220 °C.

Abstract: A process for producing flame-resistant, expandable styrene polymers (EPS) or flame-resistant extruded styrene polymer foams (XPS), wherein an organic bromine compound having a bromine content of at least 70% by weight is used as flame retardant and a liquid peroxide, hydroperoxide or a peroxide solution is used as flame retardant synergist.
