Re. Drumright et al., CYCLOALKANE PERKETAL INITIATORS FOR STYRENE POLYMERIZATION .2. DECOMPOSITION CHEMISTRY OF GEM-BIS(TERT-BUTYLPEROXY)CYCLOALKANES, Macromolecules, 26(9), 1993, pp. 2253-2258
Several ring-strained and ring-substituted tert-butylperoxy ketals wer
e synthesized. Their decomposition chemistry in ethylbenzene and their
performance in styrene polymerization as a function of structure were
investigated. The results show that the tert-butylperoxy ketal struct
ure has a significant effect upon its ability to abstract H atoms duri
ng decomposition in EB. However, no correlation was found between H-at
om abstraction efficiency of the tert-butylperoxy ketals and their abi
lity to make high M(w) polystyrene.
