摘要
通过研究纤维素醚水溶液在不同温度下的粘性行为和纤维素醚在静态空气和氮气流中的热裂解及其裂解活化能计算,探讨了改性羧甲基羟丙基纤维素醚的热稳定性。结果表明:与羧甲基羟丙基纤维素醚相比较,改性羧甲基羟丙基纤维素醚的粘度热稳定性和裂解热稳定性都有一定程度的提高。
Thermostability of Modified Carboxymethyl Hydroxypropyl Cellulose(M-CMHPC)Ether has been researched by studying viscoinetric behaviour of aqueous solutions of cellulose ethers at various temperatures, by pyrolyzing the cellulose ethers in the atmosphere of still air or N2 stream and by calculating the activation energies. The results show that compared with CMHPC.M-CMHPC has higher thermostabilities of solution viscosity and of pyrolysis.
