摘要
采用间歇法和单釜连续法合成了高固含聚合物多元醇(POP),采用动态光散射和扫描电镜研究了不同工艺下POP分散相粒子的粒径分布。实验结果表明:采用单釜连续聚合工艺能使POP产品分散相粒子粒径分布比较宽,从而能有效降低高固含POP粘度。采用单釜连续聚合工艺合成出了固含量45％,粘度为 5 900 mPa·s(25℃)的POP。
High solid content polymer polyols were synthesized by batch process and one-reactor continuous process. The distribution of dispersion particle diameter was studied by dynamic light scattering and SEM. Experiment results showed that broader distribution of particle diameter was gained by one reactor continuous process than by batch process, and POP viscosity by one-reactor continuous process was lower. POP product with 45% solid content and 5 900mPa · s （25 ℃） viscosity was synthesized by one-reactor continuous process.
