The synthesis of a copolylactide that is substituted with pendent thiol side chains is described. The copolymer is prepared by the ring-opening copolymerization of a new monomer, 3,6-bis(4-methoxybenzylthiomethyl)-1,4-dioxane-2,5-dione, with L-lactide to afford poly(lactide-co-(4-methoxybenzylthio)methylglycolide) (MBT-PL). Debenzylation of MBT-PL affords poly(lactide-co-mercaptomethylglycolide), thiol-PL. We demonstrate the modification of thiol-PL by addition to a variety of electron-deficient alkenes: N-phenylmaleimide, N-phenyl acrylate and acrylonitrile.

硫醇取代的共聚丙交酯：使用硫醇-烯的化学合成，表征和后聚合修饰†

描述了被侧基硫醇侧链取代的共聚丙交酯的合成。该共聚物通过一种新的单体，3,6-双（4- methoxybenzylthiomethyl）-1,4-二恶烷-2,5-二酮，的开环共聚来制备与大号丙交酯，得到聚（丙交酯-共- （4-甲氧基苄硫基）甲基乙交酯）（MBT-PL）。MBT-PL，得到聚（丙交酯-的脱苄基化共-mercaptomethylglycolide），硫醇-PL。：我们通过除了各种缺电子烯烃的证明硫醇-PL的变形Ñ苯基马来，Ñ -苯基丙烯酸酯和丙烯腈。
