- 70-30wt%의 열가소성인 제1 중합체와 이와는 섞이지 않는 30-70wt%의 열가소성 제2중합체를 혼합하여 혼합물을 만들어 이를 튜브형으로 압출시켜 각 중합체들이 튜브벽면내에서 서로 침투되어 있는 망상구조를 이루게 만든뒤 제2중합체를 용해시키는 용매를 사용하여 제2중합체로 이루어진 망상구조를 침출시켜 제1중합체의 망상구조로만 이루어진 다공성 튜브 벽면을 만드는 것으로 구성된, (1) 제1중합체가 방향족 폴리에테르 케톤이고, (2) 제2중합체가 방향족 폴리에테르술폰이며, (3) 혼합물에서 제1중합체의 함량이 최고인 70%일 경우 제1중합체의 용융점도가 제2중합체보다 크고 제1중합체의 함량이 최저인 30%일 경우 제2중합체의 용융점도 보다 작은 것을 특징으로하는 관형 맴브레인의 제조방법.
- 제1항의 방법으로 제조한 관형 멤브레인.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
