高分子量聚乳酸/聚丁二酸丁二醇酯多嵌段共聚物的制备与表征
biodegradable Multiblock copolymer consisting of Poly(lactic acid) and Poly(butylene succinate)
本文以羟基封端聚乳酸与聚丁二酸丁二醇酯二醇为原料，二异氰酸酯为扩链剂，通过扩链反应制备了一系列聚乳酸/脂肪族聚酯嵌段共聚物。对共聚物进行了HNMR表征，特性黏数测定以及采用GPC测定了共聚物的分子量。结果表明：采用本文的方法可合成高分子量的聚乳酸/脂肪族聚酯嵌段共聚物。
series of multiblock copolymers were synthesized through chain-extension reaction of hydroxyl terminated poly(lactic acid) with poly(butylene succinate) diol using toluene-2,4-diisocynate as a chain extender. The copolymer was characterized by 1HNMR spectrum.
