摘要: A series of waterborne polyurethane (WPU) with different soft segment structures were sythesised, and the effects structure molecular weight on degree PU microphase separation evaluated by infrared spectroscopy (FTIR) computer peak fitting. The experiment results indicated that phase between hard segments poly (ether–urethane) was more significant than (ester–urethane), based qualitative analysis N–H stretching region FTIR spectrum. And carbonyl showed lower had a higher relative amount segment, possesses degree. addition polyether PEG an internal plasticization actuating PCD chain. Therefore, it becomes easier for to conduct adjustment increased
