Abstract
Disclosed is a diurethane compound R(SO)(CH)OCONH—R—NHCOO(CH)(SO)Rproduced by a method allowing a diamine compound HNRNHto react with a chloroformate compound ClCOO(CH)(SO)Ror a method allowing a diisocyanate compound OCNRNCO to react with a hydroxyl-containing compound R(SO)(CH)OH. The diurethane compound is compounded with multivalent amine crosslinkable group-containing acrylic rubber together with a basic vulcanization accelerator to form an acrylic rubber composition. The acrylic rubber composition including the diurethane compound as a vulcanizing agent decreases a delay in the vulcanization rate due to prevention of scorching and also allows a vulcanized article to satisfy the compression set characteristics.
