摘要

<正> This paper is concerned with the synthesis of poly （ether-urethane） with pendant amino groups. The copolyether produced by ring opening copolymerization of tetrahydrofuran and epibromohydrin was treated with sodium azide in dimethylformamide to form azido substituted copolyether. The poly （ether-urethane） made from it was subjected to reduction reaction to convert azido group to amino group. The stress-strain behavior and dynamic-mechanical properties of poly （ether-urethane） containing pendant amino groups were studied.
