내수성이 우수한 아크릴 고무 및 그 제조 방법을 제공한다. (메트)아크릴산 에스테르 유래의 결합 단위 70 ~ 99.9 중량%, 가교성 단량체 유래의 결합 단위 0.1 ~ 10 중량%, 필요에 따라 다른 단량체 유래의 결합 단위 0 ~ 20 중량%를 포함하는 아크릴 고무로서, 회분량이 0.5 중량% 이하, 회분 중의 마그네슘과 인의 합계량이 30 중량% 이상이고 또한 마그네슘과 인의 중량비([Mg]/[P])가 0.4 ~ 2.5이고, 무니 점도(ML1+4, 100℃)가 10 ~ 150인 것은 특히 내수성이 우수하고, 이것을 사용한 고무 가교물도 양호한 물성을 갖는다. An acrylic rubber excellent in water resistance and a method for producing the same are provided. An acrylic rubber composed of: 70 to 99.9wt% of a bonding unit derived from (meth) acrylic acid ester; 0.1 to 10wt% of a bonding unit derived from a cross-linkable monomer; and if necessary, 0 to 20wt% of a bonding unit derived from another monomer, wherein the ash content is 0.5wt% or less, the total amount of magnesium and phosphorus in the ash is 30wt% or more, a ratio of the magnesium to the phosphorus ([Mg] / [P]) by weight is 0.4 to 2.5, and Mooney viscosity (ML1+4,100°C) of the rubber is 10 to 150 is particularly excellent in water resistance, and a rubber cross-linked product using the same is also excellent in physical properties.
