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 DEG 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.
