摘要:
通过二次回归正交旋转组合实验设计, 以单体质量分数、引发剂质量分数和反应温度为考察因素, 用响应曲面法分析了这3个因素对产物聚丙烯酰胺特性粘数的影响. 通过采用DPS数据处理软件, 建立了聚合工艺的预测模型, 预测最佳聚合工艺条件为: ω(单体)=40.0%, ω(引发剂)=0.2%, 反应温度41.6 ℃, 预测特性粘数为14.00 dL?g?1, 验证实验所得的特性粘数为12.25 dL?g?1. 两者结果相近, 说明响应曲面法优化得到的聚丙烯酰胺反相乳液聚合模型是适用可行的.
Abstract:
In order to optimize the polyacrylamide polymerization technology, the effect of monomer mass fraction, initiator mass fraction and reaction temperature on polymerization process was discussed by response surface methodology using quadratic regression orthogonally rotational combination test design. And then the prediction model was evaluated by DPS data processing software. The results indicated that monomer mass fraction of 0.4%, initiator mass fraction of 0.2%, reaction temperature of 41.6℃ were found optimum, the polymer’s intrinsic viscosity predicted of 14.00 dL?g?1, in good agreement with the experimental value of intrinsic viscosity 12.25 dL?g?1. Therefore, the model of the polyacrylamide polymerization technology optimized by response surface methodology is very reliable.
