  4. 제3항에 있어서, 상기 조성물은 중합체를 물에 용해시킨 용해임을 특징으로 하는 공정.
  5. 제3항에 있어서, 상기 조성물은 중합체를 저급 알콜에 용해시킨 용해임을 특징으로 하는 공정.
  6. 제5항에 있어서, 상기 저급 알콜은 메탄올임을 특징으로 하는 공정.
  7. 제5항에 있어서, 상기 저급 알콜은 에탄올임을 특징으로 하는 공정.
  8. 제5항에 있어서, 상기 저급 알콜은 n-프로판올임을 특징으로 하는 공정.
  9. 제1항에 있어서, 상기 양이온 교환수지는 약 2∼10%의 교차 결합제 수준을 가짐을 특징으로 하는 공정.
  10. 제1항에 있어서, 양이온 교환수지는 술폰산 양이온 교환기를 가짐을 특징으로 하는 공정.
