使用红外光谱分析了阳离子水性聚氨酯的结构及其肝素化处理后聚合物结构的变化。
The structure of cationic waterborne polyurethane and the structure changes of polymer after heparinization were characterized with infrared spectroscopy.
其研究工作分为两个部分：(1)阳离子水性聚氨酯体系的研究；(2)阴离子水性聚氨酯体系的研究。
It consists of two main parts: (1) the study on cationic waterborne polyurethane; (2) the study on anionic waterborne polyurethane.
结果表明：30%的阳离子水性聚氨酯溶液加入溶液质量15%左右的封闭型异氰酸酯的胶粘剂对金属的粘接效果较好。
The results showed:The adhesive properties were good on the metal using 30% cationic waterborne polyurethane and 15% blocked isocyanates mixing.
