Zusammenfassung:A ring-opening polymerization method of a lactone-based compound according to the present invention is a ring-opening polymerization method in which polymerization proceeds by ring-opening of a lactone compound which is a monomer. Provided is a ring-opening polymerization method of a lactone-based compound which conducts polymerization using metal-porphyrin as a catalyst under a benzyl alcohol initiator and an amine compound reaction system. The ring-opening polymerization method according to the present invention has advantages that synthesis reaction is improved through a metal porphyrin catalyst, and poly lactone aliphatic alkyl ester having excellent yield (% conversion) and high molecular weight can be prepared. 본 발명에 따른 락톤계 화합물의 개환 중합법은 단량체인 락톤 화합물의 개환에 의해 중합을 진행시키는 개환 중합법이며, 벤질알콜 개시제 및 아민 화합물 반응시스템 하에서, 메탈-포르피린(metal-porphyrin)을 촉매로 하여 중합하는 것을 특징으로 하는 락톤계 화합물의 개환 중합법을 제공한다. 본 발명에 따른 개환 중합법은 메탈 포르피린 촉매를 통해 합성 반응이 향상된 효과를 얻어, 우수한 수율(%conversion), 높은 분자량을 갖는 폴리락톤 지방족 알킬에스테르를 제조할 수 있는 장점이 있다.
