Patent number: 8288483Abstract: Disclosed is a diurethane compound R2(SO2)m(CH2)nOCONH—R1—NHCOO(CH2)n(SO2)mR2 produced by a method allowing a diamine compound H2NR1NH2 to react with a chloroformate compound ClCOO(CH2)n(SO2)mR2 or a method allowing a diisocyanate compound OCNR1NCO to react with a hydroxyl-containing compound R2(SO2)m(CH2)nOH. 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.Type: GrantFiled: January 30, 2009Date of Patent: October 16, 2012Assignee: Unimatec Co., Ltd.Inventors: Daisuke Ito, Haruyoshi Tatsu, Keisuke Kokin, Hideyuki Ono
