Biodegradable polyesters are made by synthesizing copolymers derived from biodegradable hydroxyacid monomers as well as from hydroxyacid monomers containing a functional group such as an azide group, a halogen group, a thioacetate group, and the like. Preferably, the functionalized biodegradable polyester copolymers are derived from a functionalized hydroxyacid such as a homolog of lactic acid and/or glycolic acid with the copolyester thus containing functional groups on the backbone thereof. These biodegradable polyesters can be utilized wherever biodegradable polyesters are currently used, and also serve as a polymer to which various medical and drug delivery systems can be attached.
可生物降解聚酯是通过合成来自可生物降解羟基酸单体和含有官能团的羟基酸单体的共聚物制成的,例如偶氮基团、卤素基团、硫代乙酸酯基团等。最好使用含有官能团的可生物降解聚酯共聚物来自含有官能团的羟基酸,例如乳酸和/或甘醇酸的同系物,因此共聚酯具有官能团。这些可生物降解聚酯可以用于目前使用可生物降解聚酯的任何地方,并且还可以作为可以连接各种医疗和药物输送系统的聚合物。
