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.
