Vulcanizable or vulcanized diene elastomers containing stabilizing amounts of certain bis-alkylaminophenoxyalkyl antidegradants show resistance to ozone attack. A novel class of bis-alkylaminophenoxyalkane compounds is also disclosed.

Bis-(alkylaminophenoxy)alkanes as antidegradants for rubber

Phosphinothioyl amino sulfides of the formula ##STR1## are improved accelerators for the vulcanization of rubber.

Vulcanization of rubber with phosphinothioyl amino sulfides

A process is disclosed which comprises reacting hydrogen sulfide with azolesulfonates and sulfinates to give 2-mercaptoazoles. One embodiment of the invention describes removal of oxidized forms of 2-mercaptobenzothiazole including benzothiazole-2-sulfonates from effluent by treatment with hydrogen sulfide.
