摘要: 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。

Abstract: Carboxyl vinyl terrninated-polypropylene oxide maeromers and telechelie oligorners were synthesized from hydroxyl terminated-polypropylene oxide by end group conversion. From these maeromers or telechelie oligomers and styrene, polypropylene oxide/polystyrene graft and block copolymers were synthesized and the effects of molecular structure on the damping properties of the copolymers were studied.

Key words: polypropylene oxide, earboxyl vinyl terminayed macromer, maleic anhydride, telechelic oligomer, copolymerization, damping material
