Abstract: PCT No. PCT/EP96/03633 Sec. 371 Date Jan. 29, 1998 Sec. 102(e) Date Jan. 29, 1998 PCT Filed Aug. 19, 1996 PCT Pub. No. WO97/08231 PCT Pub. Date Mar. 6, 1997A continuous process for preparing bead-form expandable styrene polymers in which the styrene is prepolymerized in bulk to a conversion of 10 to 80%, the prepolymer is dispersed in liquid form in an aqueous phase in the presence of suspension stabilizers, and the polymerization of the prepolymer is completed in an aqueous suspension to a residual styrene content of less than 2000 ppm.
