摘要：

The dissociation rate constant k(d) related to the homolytic cleavage of the C-ON bond formed between a polystyrene (PS) and 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) is determined by adopting the gel permeation chromatography peak-resolution method to the styrene polymerization with a PS-TEMPO adduct as a probe and the radical initiator tert-butyl hydroperoxide. The result was given by the Arrhenius equation, kd A exp(-E/(RT)) with A = 3.0 x 10(13) s(-1) and E = 124 kJ . mol(-1).
