본 발명은 (A) 성분: 막 형성 중합체, (B) 성분: 하기 식 (1)로 표시되는 (메트)아크릴산 에스테르 매크로 단량체 (b1)과, 기타의 단량체 (b2)를 포함하는 단량체 조성물을 중합해서 얻어지는 중합체, 및 (C) 성분: 비닐피롤리돈 단위를 포함하는 중합체를 포함하는 수지 조성물과, 상기 수지 조성물을 포함하는 제막 원액, 상기 제막 원액을 제막해서 얻어지는 다공질막, 상기 다공질막을 사용한 중공사막, 수처리 장치, 전해질 지지체 및 세퍼레이터에 관한 것이다. 본 발명에 따르면, 직경 1㎛ 이상의 큰 구멍의 형성이 억제된 균일성이 높은 세공을 가져, 분획 성능이 양호하고, 또한 높은 투수성을 갖는 다공질막, 상기 다공질막을 사용한 중공사막, 수처리 장치, 전해질 지지체 및 세퍼레이터를 제공할 수 있다. The present invention pertains to a resin composition which includes component (A): a membrane-forming polymer, component (B): a polymer obtained by polymerizing a monomer composition which includes a (meth)acrylic ester macromonomer (b1) represented by general formula (1) and another monomer (b2), and component (C): a polymer including a vinylpyrrolidone unit, a membrane-forming stock solution which includes the resin composition, a porous membrane obtained by forming with the membrane-forming stock solution, and a hollow fiber membrane, a water treatment device, an electrolyte support, and a separator which use the porous membrane. According to the present invention, it is possible to provide a porous membrane which has pores with high uniformity wherein the formation of large pores with a diameter of 1 µm or higher is suppressed and which has excellent fractionation performance and high water permeability, and a hollow fiber membrane, water treatment device, electrolyte support, and separator which use the porous membrane.
