A vulcanization accelerator, a means for accelerating vulcanization and an improved rubber product containing said accelerator therein

摘要

A vulcanization accelerator containing as an active ingredient a compound having at least one dithiocarbamoyl group, which is shown by the following general formula [I], a means for accelerating vulcanization by adding said compound and rubber products having improved quality which is attained by using said compound as a vulcanization accelerator: IMAGE [I] wherein R1 stands for an alkyl group having one to 12 carbon atoms, a cycloalkyl group having 3 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms or an aralkyl group having 7 to 13 carbon atoms, A stands for a group shown by the formula IMAGE or metallic atom; in which x represents zero or an integer of 1 to 5, R2 is an alkyl group having one to 12 carbon atoms, a cycloalkyl group having 3 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms or an aralkyl group having 7 to 13 carbon atoms; and n is one when A stands for a group shown by the formula IMAGE and is an integer of 1 to 4 corresponding to the valency when A stands for a metallic atom.
