采用了光引发聚合技术合成PAM,运用正交设计和均匀设计方法,使用数学统计软件SPSS处理实验数据,考察了光照强度、反应容器内径、转速和反应时间等因素对聚合物溶液黏度的影响。结果表明,最优化聚合条件为:光照强度0.15 mW/cm2,反应容器内径36 mm,转速10 r/min,聚合时间2 h。合成PAM相对分子质量(简称分子量,下同)在2 000万以上。
The photoinitiated polymerization was used to synthesize PAM. The orthogonal design and uniform design method were used. The experimental data were processed by SPSS software. The effects of light intensity, inner diameter of reaction vessel, rotational speed and reaction time on the viscosity of polymer solution were investigated. The results showed that the optimal polymerization conditions were as follows: light intensity 0.15 mW / cm2, inner diameter of reaction vessel 36 mm, rotation speed 10 r / min, polymerization time 2 h. Synthetic PAM molecular weight (referred to as molecular weight, the same below) in 20 million or more.
