Abstract: THE PRODUCTION OF POLYMER BEADS BY A SUSPENSION POLYMERIZATION PROCESS IN WHICH A VINYL AROMATIC MONOMER HAVING A FREE-RADICAL GENERATING CATALYST DISSOLVED THEREIN IS SUSPENDED IN AN AQUEOUS MEDIUM WITH THE AID OF A FINELY DIVIDED PHOSPHATE SUSPENDING AGENT AND HEATED TO CAUSE THE MONOMER TO POLYMERIZE INTO POLYMER BEADS IS IMPROVED BY THE ADDITION TO THE SUSPENSION OF AT LEAST ABOUT 0.01% BY WEIGHT BASED ON MONOMER OF A TERMINAL VICINAL HYDROXY-KETO COMPOUND AS SOLE EXTENDER. THE PROCESS OF THE INVENTION IS ESPECIALLY APPLICABLE IN THE PREPARATION OF LARGE SPHERICAL POLYMER BEADS.

Abstract: THE PRESENT INVENTION CONCERNS A PROCESS FOR POLYMERIZING NONOMERS AND PARTICULARLY STYRENE BY USING NEW CATALYSTS. THE INVENTION IS CHARACTERIZED BY THE FACT THAT ORGANIC SILICON DERIVATIVES, WITH A HIGHER TEMPERATURE STABILITY THAN THE CATALYST NORMALLY USED, ARE USED AS CATLYSTS. THE USE OF THESE NEW ORGANIC SILICON DERIVATIVES AS CATALYSTS PARTICULARLY IN POLYMERIZING STYRENE ENSURES A SIGNIFICANT REDUCTION IN THE RESIDUAL MONOMER CONTENT OF THE POLYSTYRENE PRODUCT, AND THUS ALLOWS SUCH A PRODUCT TO BE USED IN CONTACT WITH FOODSTUFFS.
