摘　　要：在乙醇溶液中,以稀土氯化物(PrCl3,NdCl3,SmCl3,EuCl3,TbCl3,DyCl3)、丙烯酸与8-羟基喹啉为原料合成了6种三元稀土配合物,经过元素分析、EDTA配位滴定分析、红外光谱表征,确定了稀土配合物的组成,并推测了其分子结构。将稀土配合物与甲基丙烯酸甲酯单体在偶氮二异丁腈(AIBN)引发下进行共聚反应,得到了六个稀土高分子共聚物,利用差示扫描量热法和凝胶色谱法测定了共聚物的玻璃化温度和平均分子量。Six ternary rare earth complexes RE（Ox）2AA（RE=Pr,Nd ,Sm ,Eu ,Yb ,Dy）have been synthesized by the reaction of the rare earth chloride with acrylic acid （HAA） and 8-hydroxyquinoline （HOx） in alcohol. The composition of the complexes were characterized by means of elemental analysis , EDTA complex formation titration and FTIR, and the structures of the complexes were deduced. Six new bondage copolymers RE （Ox）2AA-co-MMA have been prepared by copolymerization of the RE（Ox）2AA complex with methyl methacrylate （MMA） monomer using AIBN as an initiator. The glass temperature and average molecular weight of the copolymer RE（Ox）2AA -co-MMA was determined by DSC and GPC respectively.
