Abstract
A method for manufacturing a nitrile butadiene rubber includes: subjecting a material composition containing water, butadiene, acrylonitrile, an emulsifying agent, an initiator, and a molecular weight regulator to an emulsion polymerization reaction, so as to form an emulsion; and adding a reactive antioxidant and a non-reactive antioxidant to the emulsion to form a mixture, followed by subjecting the mixture to a coagulation process, so as to form the nitrile butadiene rubber.
