高固含量低粘度POP的合成研究

Study on Synthesis of Polymer Polyether Polyols with High Solid Content and Low Viscosity

采用双进料和双老化三釜连续工艺合成高固含量聚合物多元醇(POP),与传统工艺合成高固含量POP进行了对比。并用光子纳米粒度仪测试POP分散体粒子平均粒径和范围,分析POP分散体粒径大小对POP粘度的影响。结果表明,采用双进料工艺合成的POP产品粘度可降低1000 mPa.s,实现了制备高固含量低粘度的POP产品。

Polymer polyether polyol（POP） was prepared by three-reactor continuous process which was double- feed process and double absorption process, compared with product by the traditional process. The average grain size and scope of POP dispersion was tested by the photon nano particle size instrument. The influence of POP dispersion particle size to POP viscosity was analysed. Results showed that the viscosity of POP product by double-feed process was decreased about 1000 mPa.s. The POP product of the high solid content and low viscosity was prepared.
