ABSTRACT:
Improved radiation vulcanization of elastomers is accomplished by incorporating into the elastomer composition a polythiol, bivalent metal oxide and an aliphatic acid. The polythiol is preferably a hydrocarbon thioether thiol and is normally liquid at room temperature with a molecular weight of at least 150, said metal oxide is preferably zinc oxide and said acid is preferably stearic acid; alternatively, the reaction product of said metal oxide and acid can be used e.g., zinc stearate at appropriately increased concentration.
