摘要
用 Sm_2O_3制备了甲基丙烯酸钐和辛酸钐。通过添加或交联制得了含 Sm 的甲基丙烯酸和甲基丙烯酸甲酯共聚物。测定了 Sm 盐的元素分析、IR、TG、DTA 和它们在溶液中的荧光性质。研究了含 Sm聚合物的力学性能和荧光性质。
Sm-containing copolymers of methyl methacrylate and methacrylic acid wereprepared using samarium octanoate[Sm(OCA)_3]as additive and samarium methacrylate[Sm(MAA)_3]as crosslinking agent,respectively.The study on fluorescence properties of thecopolymers showed that there are linear relationships between fluorescence intensity and Smcontents of both two solids.Other results proved that copolymer crosslinked through samariummethacrylate is of better thermal stability,longer extension at break and stronger fluorescenceintensity at the same Sm contents than copolymer blended with Sm(OCA)_3.
