摘要 通过松香与聚醚丙烯酸酯的Diels-Alder加成产物与聚乙二醇、柠檬酸的缩聚反应,合成出松香基聚醚酯弹性体,产物采用红外、拉伸、DSC和TGA进行了表征。TGA测试表明,松香基聚醚酯弹性体的10%热失重温度在300℃以上,拉伸测试表明,拉伸强度为0.26~0.62 MPa,断裂伸长率为338%~458%。 Rosin-based poly(ether ester) elastomers were prepared from(R-PEGDA),citric acid and polyethylene glycol(PEG) via polycondensation reaction.TGA plots of the product showed that the temperature of 10% mass loss could be up to 300 ℃.The elastomers exhibited a wide range of tensile stress at break 0.26~0.62 MPa and elongation at break of 458%~338%.
