We modified poly(butylene succinate) (PBS) with sugar-based monomer isosorbide to improve the bond strength between PBS and metal interfaces and thereby alleviate the environmental problems caused by nondegradable hot-melt adhesives. We analyzed the efficiency of different catalysts in the synthesis of poly(butylene--isosorbide succinate) (PBIS) copolyesters. The thermal stability, thermodynamic characteristics, and melting viscosity of PBIS copolyesters were systematically evaluated by characterization. The results indicate that isosorbide can greatly improve the bond strength of the interface between PBS and the iron plate when copolyesters are used as hot-melt adhesives.
我们用糖基单体异山梨醇对聚丁二酸丁二醇酯(PBS)进行改性,以提高PBS与金属界面之间的结合强度,从而缓解由不可降解热熔胶引起的环境问题。我们分析了不同催化剂在聚(丁二酸-异山梨醇丁二醇酯)(PBIS)共聚酯合成中的效率。通过表征系统地评估了PBIS共聚酯的热稳定性、热力学特性和熔融粘度。结果表明,当共聚酯用作热熔胶时,异山梨醇可以大大提高PBS与铁板之间界面的结合强度。
