摘要
基于端羟环氧乙烷 -四氢呋喃无规共聚醚、异佛尔酮二异氰酸酯以及 1,4-丁二醇 ,采用熔融二步法合成了一系列新型的用于固体推进剂的热塑性聚氨酯弹性体。以 DSC及 FTIR为主要测试手段 ,建立了影响热塑性弹性体性能的微相分离程度的定量方程 ,并以此对所合成的
A new type thermoplastic polyurethane elastomer for using as binder in solid propellent were prepared with melt-prepolymerization method based on ethylene oxide-tetrahydrofuran random copolyehter,isophorone diisocyanate and 1,4-butanediol.Quantitative estimate of phase segregation were discussed with quantitative equation established based on DSC and FTIR results.
