Curable acrylic rubber containing dibutylaminotriazine thiol and 9,10-dihydro-9-oxa-10-phosphapenathrene-10-oxide

摘要

A curable acrylic rubber composition which is comprised of (A) an acrylic polymer and, as a curing agent, a combination of (B) a polymer of a dibutylaminotriazine thiol with (C) 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10 -oxide or a reaction product thereof with a carbonyl compound. This rubber composition is not scorched at room temperature, but is cured at a high rate of reaction at a rubber curing temperature.
