聚乙二醇—硝酸镧配位聚合物的表征研究

The Characterization Investigation of Polyethylene Glycol-Lanthanum Nitrate Coordination Polymers

摘要: 以聚乙二醇(PEG)为配位体,首次合成了三价稀土金属镧与PEG的配位聚合物。实验测定了该配位聚合物的红外光谱、示差扫描量热谱(DSC)、热失重分析(TGA)和凝胶渗透色谱(GPC),并就配位反应、热分解以及配位前后分子流体力学体积的变化进行了讨论。

Abstract: Polyethylene glycol-Lanthanum nitrate coodination polymers have beensynthesized and characterized by IR, NMR, DSC, TGA and GPC methods. The exper-iment results have been disussed concerning the coordination reaction, thermal decom-position and the change
