用溶液聚合法合成了含有五种不同扩链剂,软段为胺端基聚环氧丙烷的聚脲氨酯和聚脲。用示差扫描量热计法得热容变Δc_(?),动态力学温度谱等数据,说明不同扩链剂对嵌段共聚物性质及微相分离的影响。
Polyurethanes and polyureas containing five different chain extenders and soft segment amine terminated poly (propylene oxide) were synthesized by solution polymerization. The differential scanning calorimeter (ΔC_ (?)) And dynamic mechanical temperature (DSC) data were used to demonstrate the effect of different chain extenders on the properties of the block copolymer and the micro-phase separation.
