ABSTRACT

Conclusions3,6-Di-tert-butyl-2-hydroxyphenoxyl radicals (QH.) were detected by EPR spectroscopy in a mixture of 3,6-di-tert-butylpyrocatechol (QH2) and 3,6-di-tert-butyl-1,2-benzoquinone (Q) in the polymerization of methyl methacrylate. The rate constant for the reaction QH2 + Q⇄ 2QH. and the rate contants for the forward and back reactions were determined at 60°C.
