FIELD: chemistry.

SUBSTANCE: invention relates to acrylic rubber compositions which are used to make industrial rubber products, e.g., rubber hose, sealing articles, rubber vibration insulators etc. The composition contains carboxyl group-containing acrylic rubber, a diazabicycloalkene compound, a polyamine compound and a tertiary amine compound of formula (1), where each of R₁, R₂ and R₃ independently denotes a substitute containing at least one saturated aliphatic hydrocarbon or an unsaturated aliphatic hydrocarbon with a linear structure, a branched structure or a cyclic structure, or a benzyl group. The polyamine compound is an aromatic polyamine of formula (2): H₂N-Ph-M-Ph-NH₂ (2) where M denotes O, S, SO₂, CONH or O-R-O; R in O-R-O is Ph, Ph-Ph, Ph-SO₂Ph, (CH₂)_m, m ranges from 3 to 5, Ph-CH₂-C(CX₃)₂CH₂-Pn, where X is H or F, or (CH₂)C(CH₃)₂(CH₂); Ph denotes a benzene ring.

EFFECT: good curing parameters and excellent combination of processability, mechanical properties of rubber and compression set of acrylic rubber compositions and curing products thereof.
