Claims (4)

  1. 구형입자들을 제조하는데 있어서, 소수성 폴리아미노산을 유기 용매내에 용해시켜 용액을 제조하는 공정; 상기 용액을 수성 매질내에 가하고 매질을 교반함으로써 유기용매를 증발시키는 한편 수성 매질내에 분산된 폴리아미노산 구형입자들의 분산액을 수득하는 공정; 및 분산액으로부터 폴리아미노산 구형 입자들을 수거하는 공정을 특징으로 하는 폴리아미노산 구형입자들의 제조방법.
  2. 제1항에 있어서, 용액에 폴리아미노산과는 섞이지 않고 상기 폴리아미노산을 용해시킬 유기용매와는 섞이며 및 수성 매질내에 용해되지 않는, 및 유기용매 및 수성매질 보다 높은 비점을 갖는 첨가제를 첨가함을 특징으로 하는 방법.
  3. 제1 및 2항에 있어서, 폴리아미노산의 구형입자들이 수득될때 용액의 점도 조절제를 첨가함을 특징으로 하는 방법.
  4. 제3항에 있어서, 점도 조절제가 수용성 중합체를 함유함을 특징으로 하는 방법.
