摘要： 合成了顺丁烯二酸酐酯化β-环糊精与苯乙烯的共聚物及其金属配合物。 利用红外、紫外、元素分析、差示扫描量热法及热失重分析法对其进行了结构表征和性能测试。 这种含有β-环糊精的共聚物金属配合物作为脲酶抑制剂，对大豆脲酶催化尿素水解的抑制效果显著，其铜金属配合物为4 g/L时，抑制率达96.67%。

关键词: 环糊精共聚物, 大豆脲酶, 脲酶抑制剂, 共聚物金属配合物

Abstract: β-Cyclodextrin(β-CD) copolymers and its metal complexes were synthesized via the polymerization between (6-O-butene diacid ester)-β-cyclodextrin and styrene. Their structures and properties were characterized by infrared spectrum(IR), ultraviolet spectrum(UV), elemental analysis(EA), differential scanning calorimeter(DSC) and thermogravimetry(TG). β-CD copolymers metal complexes used as urease inhibitors were investigated and showed prominent inhibition efficacy. The inhibition ratio of copolymer-Cu2+ complex was 96.67% with a loading of 4 g/L.

Key words: cyclodextrin copolymer, soybean urease, urease inhibitor, copolymer metal complex
