Abstract A simple synthetic route is used for the preparation of hydroxyl functionalized polyesters from an AB-type monomer carrying an epoxy and carboxylic acid group. A systematic study of the reaction conditions suggested that tetrabutylphosphonium bromide was the better polymerization catalyst to obtain the highest conversion of linear polymers with moderate molecular weights. Enzymatic catalyst (CALB), in contrast, yielded branched polymers with polyether units. The synthesized polymers were structurally characterized in detail, using model compounds previously synthesized, by 1H, 13C, and 19F NMR. Polyesters were characterized by FTIR, SEC, DSC and TGA too. The post-polymerization modification of the reactive hydroxyl sites present along the polymer backbone with N-Boc protected l -phenylalanine and l -serine was essayed to test the ability of these polyesters to prepare polymer bioconjugates.

衍生自 10-十一碳烯酸的羟基官能化可再生聚酯：聚合物结构和聚合后改性

摘要 采用一种简单的合成路线，由带有环氧基和羧酸基团的AB 型单体制备羟基官能化聚酯。对反应条件的系统研究表明，四丁基溴化鏻是获得中等分子量线性聚合物最高转化率的更好的聚合催化剂。相比之下，酶催化剂 (CALB) 产生具有聚醚单元的支化聚合物。使用先前合成的模型化合物，通过 1H、13C 和 19F NMR 对合成的聚合物进行了详细的结构表征。聚酯也通过 FTIR、SEC、DSC 和 TGA 进行表征。
