Abstract: The invention relates to the method for producing expandable polystyrene with a molecular weight Mw in excess of 170000s/mol. According to the invention, a styrene polymer melt containing an expanding agent and having a temperature of at least 120 °С is passed through a spinneret comprising bores, which diameter at the spinneret exit measures a maximum 1.5 mm and then is granulated.
