Carboxyl vinyl terminated polytetrahydrofuran macromers and telechelic oligomers were synthesized from hydroxyl terminated polytetrahydrofuran by end group conversion. From these macromers or telechelic oligomers and styrene polytetrahydrofuran/polystyrene segmented and graft copolymers were synthesized and the effects of molecular structure on the damping properties of those copolymers were also studied. 相似文献

聚环氧丙烷/聚苯乙烯接枝与嵌段共聚物的合成和阻尼性能 总被引:1,自引:0,他引:1
合成接枝和嵌段共聚物是研究阻尼材料的重要途径。可以在较广的范围内,调整共聚物的结构,使之具有良好的阻尼性能。我们选择聚环氧丙烷与顺丁烯二酸酐反应,制成端乙烯基大分子单体和遥爪低聚物,与苯乙烯共聚,制成接枝和交联嵌段共聚物。探讨了不同结构因素对阻尼性能的影响规律,研究结果有益于阻尼材料的分子设计。 相似文献
