Beschreibung
Zusammenfassung:	The invention relates to a method for producing expanded polyolefin particles, according to which polyolefin granulate is impregnated with a volatile expanding agent in suspension under pressure and then relaxed. The suspension medium has a lower density than the polyolefin granulate and the suspension is practically free of suspension stabilisers.
