Abstract
PURPOSE: To prevent the blooming of rubber containing insoluble sulfur as a valcanizing agent, by compounding the base rubber with a specific amine-type age resistor, and keeping the amount of the primary amine in the composition below a specific level.
CONSTITUTION: The aging and blooming of a rubber is prevented, effectively, by compounding 100pts.wt. of a base rubber with 0.5W5pts.wt. of an amine-type age resistor essentially free from or containing ≤3% of primary amine [e.g. poly-2,2,4- trimethyl-1,2-dihydroquinoline (primary amine content;2.3%)], and keeping the primary amine content in the rubber composition to ≤0.5wt% (determined by potentiometric titration).
