| 摘 要： | 以丁二酸(SA)、1,4-丁二醇(BD)和二甘醇(DEG)为原料,通过直接聚合法合成了可生物降解的聚丁二酸丁二醇/二甘醇酯(PBDGS)。采用1H-NMR,GPC,DSC等对产物进行了表征,研究了物料配比对共聚酯热性能、力学性能、降解性能和亲水性的影响。结果表明,DEG的引入能够有效抑制聚酯链段的结晶能力,同时改善材料的亲水性,使其降解性能较纯PBS有显著提高。

| Abstract: | Biodegradable aliphatic poly(butylene succinate-co-diethylene succinate)(PBDGS) were synthesized from succinate acid and 1,4-butanediol/diethylene glycol through direct polymerization.The products were characterized with 1H-NMR,GPC and DSC,etc.The influence of monomer ratio on thermal properties,mechanical properties,degradability and hydrophilicity of the copolymers were studied.The results showed that the introduction of DEG can suppress the chain crystallizability and improve hydrophilicity of PBDGS.The ... |
