Vulcanization and Accelerators [PDF Document]
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links (of sulfur).

The mechanism of vulcanization and the action of
Vulcanization as a process of chemical crosslinking formation occurs when this reaction proceeds with radicals formation (light effect, redox systems). Disulfides and sulfenamides cause the effect of vulcanization passing through the stage of hydrogen separation from α-methylene group, and the formation of polymer radicals.
