摘要: The invention provides a process for preparing expandable styrene polymers which comprises the steps of:(a) adding an aqueous phase comprising a suspension stabilizer and an organic phase comprising styrene and an initiator to a reactor,(b) commencing the addition of a blowing agent at a styrene conversion in the range from 40 to 70% and adding the blowing agent over a period ranging from 30 to 60 minutes,(c) adding a stabilizer to stabilize the bead size distribution of the expandable styrene polymer at a styrene conversion in the range from 65 to 99%.
