摘要
A process for non-modifying recycling of styrene polymers, comprising the steps: a) melting the possibly finely reduced styrene polymers in an extruder, and b) extruding the melt thus obtained, to which expanding agents and/or the usual additives may be added, in which melting is performed in the presence of 0.01 to 4 wt % in relation to the styrene polymer of bismaleic imides, trismaleic imides and/or maleic imides with more than three imide groups.
