硝基环氧丙烷可在三氟化硼乙醚-丁二醇系统催化下顺利地进行聚合和共聚合,得到侧链带硝基甲基的端羟基聚醚。预聚物与二异氰酸酯和甘油反应可进一步交联成为具有一定强度和弹性的胶片。研究了预聚物和胶片的某些特性。
Nitropropane oxide in the boron trifluoride ether - butanediol system catalyzed by the smooth polymerization and copolymerization, to give the side chain with nitromethyl hydroxyl terminated polyether. The prepolymer reacts with the diisocyanate and glycerin to further crosslink into a film of a certain strength and elasticity. Some properties of prepolymers and films were studied.
