Bead-form expandable styrene polymers containing a styrene polymer having a mean molecular weight (weight average) of less than 130x103 and a steep high-molecular-weight flank of the molecular-weight distribution curve, and 0.15 to 1.5 mol of a C3- to C6-hydrocarbon as blowing agent, and, if desired, customary additives in effective amounts, are distinguished by a particularly high expansion capacity. |
