| 摘 要： | 聚（２，６ 二甲基 １，４ 苯醚）（ＰＰＯ）离聚体（磺化或羧化聚苯醚）／聚（苯乙烯 ｃｏ ４ 乙烯吡啶（ＰＳＶＰ）共混物的溶液行为研究表明，与对应的ＰＰＯ／ＰＳＶＰ共混物相比，这两个系列的共混物都表现出较高的比浓粘度．这是由于聚苯醚离聚体上的酸基发生质子转移，产生了酸根阴离子和吡啶基阳离子，两组分间的酸 碱相互作用导致了分子间的缔合，从而使比浓粘度提高．

| Abstract: | The solution behavior of poly(2,6 dimethyl 1,4 phenylene oxide)(PPO)ionomer(carboxylated PPO or sulfonated PPO)/poly(styrene co 4 vinylpyridine)(PSVP)blends were investigated.The reduced viscosities of both the two series of blends were higher than those of comparable blends composed of PPO and PSVP.These were attributed to the acid base interactions resulting from proton transfer between the acid groups of the PPO ionomer and the vinylpyridine groups of the PSVP. |
