Description

Relation between activities (i.e., delayed action, rate of vulcanization, etc.) and chemical structures of sulfenamide-type delayed action vulcanization accelerators for rubber were quantum chemically studied.<br>Four parameters, which affect greatly on activities of the accelerators, were derived. They were electrophilic reactivity indices on sulfur atoms, radical reactivity indices on nitrogen atoms, π-bond orders between sulfur and nitrogen atoms, and π-electron densities on nitrogen atoms of sulfenamide linkages.<br>From those results, some new vulcanization accelerators of improved delayed action could be discovered.<br>Reaction mechanisms of the accelerators were also discussed briefly.
