The synthesis of well‐defined propargyl‐functional aliphatic polycarbonates is achieved via the organocatalytic ring‐opening polymerization of prop‐2‐yn‐1‐yl 2‐oxo‐1,3,6‐dioxazocane‐6‐carboxylate (P‐8NC) using a wide variety of commercially available or readily made, shelf‐stable organocatalysts. The resulting homopolymers show low dispersities and end‐group fidelity, with the versatility of the system being demonstrated by the synthesis of telechelic copolymers and block copolymers with molar mass up to 40 kDa.

八元N环碳酸酯的开环聚合有机催化合成炔烃官能脂肪族聚碳酸酯

定义明确的炔丙基官能脂肪族聚碳酸酯的合成是通过对2--2-炔-1-基-2-氧代-1,3,6-二恶唑烷-6-羧酸酯（P-8NC）进行有机催化开环聚合来实现的使用各种可商购或易于制造的，耐贮存的有机催化剂。所得均聚物显示出低分散性和端基保真度，该系统的多功能性由摩尔质量高达40 kDa的远螯共聚物和嵌段共聚物的合成证明。
