2,6-Ditert-butyl-4-methyl-4-(3,5-ditert-butyl-4-hydroxybenzyl)-2,5-cyclohexadiene-1-one (III) is formed from BHT (I) as a minority transformation product during the ageing of BHT doped polyethylene. To determine the structure of III and to obtain an authentic model compound, synthesis was performed using an indepdndent procedure. The transformation product III is reported for the first time and can be considered as a source of secondary phenoxy radicals detected in aged polyolefins. [ABSTRACT FROM AUTHOR] |
