<jats:p>The crosslinking of various halogen-containing rubbers with triazine thiols and metal compounds was investigated, with the following conclusions: (1) Triazine thiols react with halogen-containing rubbers after reacting with metal compounds to form salts. (2) Reactivity of triazine thiols and metal compounds increased with a decrease in thiol pKa, and with an increase in the thiol anion basicity. (3) In this crosslinking, the reactivity of rubbers increased in the order: FR &lt; CPE &lt; PVC &lt; CIP &lt; CO &lt; ECO &lt; CAR &lt; CR. (4) In the crosslinking of CAR, the ether groups in a side chain activated the crosslink site. The sequence of oxyethlene units in ECO was found to activate the crosslinking agents. (5) The active halogen-containing rubbers such as CR and ECO were crosslinked by a combination of inactive F, MgO, and retarders such as Santogard PVI. (6) On the contrary, the crosslinking of rubbers containing inactive halogen, such as soft PVC and FR, was carried out by a combination of active DB, MgO, and accelerators such as polyethylene glycols or onium salts.</jats:p>
