摘　　要：以聚醚多元醇为原料 ,通过聚氨酯预聚体的方法制得了可湿气固化的硅烷化聚醚 ,研究了温度和时间对反应的影响 ,以及不同NCO/OH比值对固化物力学性能的影响。结果表明 。Moisture curable silylated polyethers were obtained by the method of urethane prepolymer,reaction temperature,time and different ratio of NCO/OH were studied,the results showed that the different mechanical properties of cured polymer could be produced by the different ratio of NCO/OH.

关 键 词：聚氨酯预聚体 硅烷化聚醚 湿气固化 密封剂
