Ring-opening polymerization process for cyclo-lactone compound and metal-porphyrin catalyst for ring-opening polymerization

摘要

The 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 as a monomer, and under a benzyl alcohol initiator and an amine compound reaction system, metal-porphyrin as a catalyst To provide a ring-opening polymerization method of a lactone-based compound, characterized in that the polymerization. The ring-opening polymerization method according to the present invention has an advantage in that the synthesis reaction is improved through the metal porphyrin catalyst, and a polylactone aliphatic alkyl ester having an excellent yield (% conversion) and a high molecular weight can be prepared.
