- 폴리-[α-히드록시 (아크릴, 크로톤 또는 아크릴+크로톤)산]의 폴리락톤의 제조 방법에 있어서, 알킬 아크릴레이트 또는 알킬 크로토네이트 또는 그 혼합물을 상응하는 2,3-디클로로프로피온산 알킬에스테르 또는 2,3-디클로로부탄산 알킬 에스테르 또는 그 혼합물로 염소화 시키고; 결과로서 생성된 2,3-디클로로프로피온산 알킬에스테르 또는 2,3-디클로로부탄산 알킬에스테르 또는 그 혼합물을 수성 염기로 처리하여 탈염화수소반응 및 상응하는 염으로 전환시키며; 이어서, 산성화시키고; 중합시키며; 산성 조건하에서, 폴리-[α-히드록시(아크릴, 크로톤 또는 아크릴+크로톤)산]의 폴리락톤으로 전환시키는 단계들로 구성되고, 중간 생성물의 분리없이 수행되는 상기의 제조방법.
- 제1항에 있어서, 아크릴산 알킬에스테르 또는 크로톤산 알킬에스테르 또는 이들의 혼합물을 염소화 촉매로서 사용되는 N-치환된 카르복실산 아미드 존재하에 염소화 처리함을 특징으로 하는 방법.
- 제1항에 있어서, 탈염화수소 반응 및 염 형태로의 전환 반응이 알칼리 금속 수산화물 또는 암모늄 수산화물의 수용액 존재하에 수행되는 것을 특징으로 하는 방법.
- 제1항에 있어서, 산성화 처리가 pH 1내지 5로 만들 수 있는 유기 강산 또는 무기 강산을 첨가하여 수행되는 것을 특징으로 하는 방법.
- 제1항 내지 제4항중 어느 한항에 있어서, 수득된 폴리락톤을 수성 염기를 사용하여 상응하는 폴리-(α-히드록시-카르복실레이트)로 가수분해시킴을 특징으로 하는 방법.
- 제5항에 있어서, 폴리락톤을 모액으로부터 분리함이 없이 가수분해함을 특징으로 하는 방법.
