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 bead-shaped expanded polystyrene by suspension polymerisation of styrol in the presence of 1 to 5 wt. % of a hydrocarbon with 4 to 6 C atoms and 0.5 to 3.5 wt. % of a saturated aliphatic hydrocarbon with a boiling point above 70°C, but in the absence of a chain initiator, giving rise to a reduction in the molecular weight of the polystyrene.

Abstract: Preparation of styrene polymers containing a propellant by polymerisation of styrene with comonomers, in aqueous suspension, with addition, (at start or during polymerisation) of amphiphilic organic emulsifying agent containing hydrophilic and hydrophobic groups, or a polymer carrying a polar group, (miscible in water), so the suspended styrene droplets contain finely distributed water particles.

Abstract: The invention relates to a method for producing expandable polystyrene with a molecular weight Mw in excess of 170,000 g/mol. According to the invention, a styrene polymer melt containing an expanding agent and having a temperature of at least 120 ~C is passed through a spinneret comprising bores, whose diameter at the spinneret exit measures a maximum 1.5 mm, and is then granulated. The invention also relates to expandable styrene polymers (EPS) with a molecular weight Mw of more than 170,000 g/mol and between 0.05 and 1.5 wt. % inherent moisture.
