Cure systems for rubber compounds - Rodgers, Michael B.
In summary, for semi-EV cure systems in butyl compounds, use of alkylphenol disulfide polymer cured compounds may allow improvements in: 1. Reversion resistance. 2. Adhesion. 3. Better retention of aged properties. Table VIII tabulates the cure systems apparent activation energy data, showing this is higher for the alkylphenol disulfide cured compounds.

US3968062A - Use of para-tert. butyl phenol disulfide for
An improved process for preparing chlorobutyl rubber compositions employs, as curing agent, para-tert. butyl phenol disulfide having a sulfur content in excess of about 27 wt% and a softening point not less than 80°C. Para-tert. butyl phenol disulfide is a solid substance which, unlike other commercially employed alkyl phenol sulfides, is a non-tacky brittle solid which does not deteriorate ...

Zinc oxide particles: Synthesis, properties
Zinc oxide is also used as a curing or cross-linking agent for halogen-containing elastomers such as neoprene or polysulfides [150]. Metallic oxides not only change the rate of cure but also the ‘scorch’ (i.e. premature vulcanization caused by heat during rubber processing) in neoprene [151].
