본 발명은 일반식(II)의 단량체를 포함하는 기본중합체에 일반식(I)의 단량체를 그라프트시킴을 특징으로 하는 피혁처리에 유용한 그라프트 공중합체에 관한 것이다. 상기식에서, R및 R는 탄소수 2내지 25의 탄화수소 그룹이다(단, 그룹 R및 R의 반 데르 발스 용적값은 최대 용적값의 30%이하로 상이하다. The invention concerns graft copolymers, useful for the treatment of leather, comprising monomers of the formula (* CHEMICAL STRUCTURE *) grafted onto a base polymer comprising monomers of the formula (* CHEMICAL STRUCTURE *) wherein R1 and R2 stand for a hydrocarbon group having 2 to 24 carbon atoms, with the proviso that the groups R1 and R2 have van der Waals volumes which differ from one another by less than 30 percent.
