NDI型聚氨酯弹性体的研制

摘要

The pre-polymer synthesized with NDI and a special polyester polyol could be stored stably for 6 months at room-temperature .Polyurethane elastomers prepared with the pro-polymer have good mechanical and re-silience properties , and the dynamic mechanical properties are excellent .%采用自制聚酯多元醇合成了可常温稳定储存6个月的NDI（1，5-萘二异氰酸酯）型预聚体，使用该类型预聚体可制备出具有良好力学性能和回弹性、优异动态力学性能的NDI型聚氨酯弹性体。
