Abstract
In silicone rubber crosslinked with bis(2,4-dichlorobenzoyl) peroxide (DCBP, as initiator about 0.1% of DCBP is converted into polychlorobip henyls (PCBs). The PCB content in silicone rubber determined by high r esolution gas chromatography (HRGC) after its destruction by HF is aro und 10 mg/kg. 29 PCB congeners were detected. Instead of the expected PCB-47, lower chlorinated congeners are predominant. Some possible pat hways of their origin are presented.
