N-(hydrocarbyl thiophosphoryldithio)-imide vulcanization agents and accelerators

摘要

N-(hydrocarbyl thiophosphoryldithio)-imides such as N-(O,O- diisopropyl thiophosphoryldithio)-phthalimide are used as accelerators with, or as a partial or total replacement for, the elemental sulfur used in conventional sulfur vulcanization systems for diene rubbers.
