Polysulfide polymer is cured by converting mercaptan (-SN) groups to disulfide (-S-S-) bonds.
Polysulfide polymer is cured by converting mercaptan(-SH) end groups to disulfide (-S-S-)bonds.
Liquid polysulfide polymers, such as the Thiokol LP series (Morton International), are also able to form reactive crosslinking short chains through accelerator peptization of the sulfurs in the polymer chain.
