Lactone polymerisation / Lactone polymerization
内酯聚合 (nèi zhǐ jù hé)
Lactone polymerization is a type of ring-opening polymerization that involves the reaction of lactone monomers. Lactones are cyclic esters. During polymerization, the ring is opened, and the monomers link together to form a polymer chain. Lactone polymerization is used to synthesize polyesters, which have various applications in biodegradable plastics, drug delivery systems, and resorbable sutures.
内酯聚合是一种开环聚合，涉及内酯单体的反应。内酯是环酯。在聚合过程中，环被打开，单体连接在一起形成聚合物链。内酯聚合用于合成聚酯，聚酯在可生物降解塑料、药物输送系统和可吸收缝线中具有多种应用。
