摘要(Abstract):

以L-乳酸与聚乙二醇为原料,熔融共聚,再固相聚合得到聚乳酸-聚乙二醇共聚物(PLEG)。用凝胶渗透色谱(GPC)、红外光谱(FTIR)、熔点测试、差示扫描量热法(DSC)、吸湿率测试等手段对其进行表征,发现相同条件下,聚乳酸-聚乙二醇共聚物吸湿率高于聚乳酸。
Using poly(lactic acid) and polyethylene glycol as raw material, PLA/PEG copolymer were synthesized via melt copolycondensation and solid state polycondensation. Their relative molecular weight, structure and properties were systematically characterized and compared by GPC,FTIR,melting point, moisture absorption and DSC. Under same synthetic conditions, moisture absorption of PLA/PEG copolymer was higher than poly(lactic acid).
