摘要：the invention concerns a process for the production of particulate,
expandierbaren propylenpolymerisaten by mixing propylenpolymerisat - melt with avolatile organic blowing agent and a nucleierungsmittel in an extruder, and the pressingand granulation of the schmelzestrangs in a water bath at a temperature and pressure iscarried out.with virtually no foaming granules takes place.
