Abstract

A method of vulcanizing rubber, the method comprising adding to un-vulcanized rubber a complex comprising a disulfide compound having an acidic hydrogen and zinc oxide and vulcanizing the rubber, wherein the oxygen atom of the zinc oxide is covalently bound to the acidic hydrogen of the disulfide compound.

Claims (6)

1. A method of vulcanizing rubber, the method comprising adding to un-vulcanized rubber a complex comprising a disulfide compound having an acidic hydrogen and zinc oxide and vulcanizing the rubber, wherein the oxygen atom of the zinc oxide is covalently bound to the acidic hydrogen of the disulfide compound.

2. The method of claim 1 , wherein the disulfide compound is an alkylphenoldisulfide compound.

3. The method of claim 2 , wherein the complex is in crystal form when combined with the un-vulcanized rubber.

4. A vulcanizing accelerator comprising a complex comprising a disulfide compound having an acidic hydrogen and zinc oxide, wherein the oxygen atom of the zinc oxide is covalently bound to the acidic hydrogen of the disulfide compound.

5. The vulcanizing accelerator of claim 4 , wherein the disulfide compound is an alkylphenoldisulfide compound.

6. The vulcanizing accelerator of claim 5 , wherein the complex is in crystal form.
