- 폴리 카보네이트 소중합체와 페놀화합물를 가성알칼리 존재하에 반응시켜 폴리 카보네이트를 제조하는 방법에 있어서, 제1반응 지역에서 가성 알칼리와 페놀화합물을, 알칼리와 페놀화합물중의 수산기의 당량비(알칼리 : 수산기)가 0.9 : 1-1.8 : 1로 되도록 도입하여 중합반응시켜, 점도 평균 분자량이 3,000-15,000인 폴리카보네이트를 제조한다음, 제1반응지역에서 제조한 폴리카보네이트를 함유한 반응혼합물을 제2반응 지역에 도입함과 동시에, 가성알칼리를 보충하여, 그 제2반응지역에 있어서의 가성 알칼리 농도를 0.05-0.7N로 조절하여 중합반응을 실시하는 것을 특징으로 하는 폴리카보네이트 제조방법.
- 제1항에 있어서, 제1반응 지역에서의 중합반응을 실시한후, 동일 반응지역에서 가성알칼리를 보충하여, 가성알칼리 농도를 0.05-0.7N로 조절하여 중합반응을 실시하는 폴리카보네이트 제조방법.
- 제1항에 있어서, 제1반응 지역과 제2반응지역에 있어서의 중합반응이 서로 다른 반응기에서 실시되는 폴리카로네이트 제조방법.
- 제1항에 있어서, 제1반응 지역과 제2반응 지역에 있어서의 중합반응이 용매의 존재하에 실시되는 폴리카보네이트 제조방법.
- 제1항에 있어서, 제1반응 지역 또는 제2반응 지역에 있어서의 중합반응이, 선형혼합기, 오리피슨 믹서, 정적 혼합기 및 교반조에서 선택된 반응기내에서 실시되는 폴리카보네이트 제조방법.
- 제1항에 있어서, 제1반응 지역에 있어서의 중합반응 이 반응온도 10-50℃에서 실시되는 폴리카보네이트 제조방법.
- 제1항에 있어서, 제2반응 지역에 있어서의 중합반응이 반응온도 10-50℃에서 실시되는 폴리카보네이트 제조방법.
- 제1항에 있어서, 폴리카보네이트 소중합체의 수평균 분자량이 300-2,500인 폴리카보네이트 제조방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
