Abstract
The present invention relates to a method for preparing a nitrile-based rubber, by which the nitrile-based rubber is prepared by polymerizing a monomer mixture comprising an α,β-unsaturated nitrile-based monomer and a conjugated diene-based monomer, in the presence of an initiator and an emulsifier comprising a C30 to C60 compound having two or more carboxyl groups, a nitrile-based rubber prepared thereby, and a nitrile-based rubber composition comprising the nitrile-based rubber.
