Abstract:
The invention relates to a method for producing expandable thermoplastic polymer particles by post-impregnating thermoplastic polymer particles that contain at least one styrene polymer and at least one polyolefin, using a blowing agent. Said post-impregnation is predominantly carried out in the gas phase.
