摘要：
A carbamate ester compound represented by the general formula:
Z—OCONH(CH2)nNHCOO—Z [I]
wherein Z is [i], [ii], or [iii] below, and n is an integer of 2 to 10,
(wherein R1 and R2 are each independently a lower alkyl group having 1 to 5 carbon atoms, R3 is a hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, and a is 1 or 2). The carbamate ester compound is used as a vulcanizing agent for carboxyl group-containing acrylic rubber and improves the delay of the vulcanization rate by scorch suppression.
