Zusammenfassung:	PURPOSE:To provide a chlororubber-compounded composition excellent in resistances to compression set and ozone without impairing its scorch resistance, useful for automotive parts etc., comprising a chlororubber, curing agent, thiourea-based curing promoter, antioxidant, and peroxide compound at specified proportion. CONSTITUTION:The composition can be obtained by compounding (A) 100 pts.wt. of a chlororubber such as chloroprene rubber, (B) 3-10 pts.wt. of a curing agent such as zinc oxide, (C) 0.5-2.0 pts.wt. of a thiourea-based curing promoter, (D) 0.5-4.0 pts.wt. of an antioxidant such as p-phenylenediamine-based compound, and (E) 0.05-1.0 pt.wt. of a peroxide compound such as di-t-butyl peroxide.
