SURFACE TREATED CERIC OXIDES; SILICONE CLASTOMERS WITH IMPROVED FLAME RESISTANCE, CONTAINING SAID CERIC OXIDES

摘要

the present invention relates to cerium oxide containing surface and forms y3sio grafts y3si (osiz2) n -, o -,y and z representing groupementss monovalent hydrocarbon radical such as alkyl with 1 to 10 carbon atoms.the cerium oxide can be obtained by treatment with hexamethyldisilazane.silicone compositions comprising cerium oxide can be treated as the acquisition of silicone, elastomer with improved flame resistance.
