说明：
In this paper, firstly, a quite good synthesis method of aqueous polyurathane emulsion is got by changing the technology, prescriptiom, etc. This meth ...展开
od has some characteristic as below: simple technology, low comumption of organic solvent, low production cost, relatively high solid content and good stability of the emulsion, easy to cast film, and can adjust the properties ofthe film as desire, etc. Then, with the determination of DSC, mechanical properties, water absorbtion ratio, ete, the relationships of the "structure-microphase seperation-properties" of ionic polyurathane is investigated detailed. It may provide some theoretic basis for the synthesis and applications of aqueous polyurathane emulsion. 收起
