| 摘 要： | 采用光引发聚合技术,选取合适的光引发剂进行丙烯酰胺(AM)反相微乳液聚合。用UV光引发AM/水/白油/(Span80+OP-10)体系聚合,所得聚合物粘均相对分子质量可达106。考察了光引发剂类型及质量分数、单体质量分数、乳化剂质量分数和聚合时间等对聚合反应的影响,得到了光引发合成聚合物的较优工艺条件。通过红外光谱法鉴定出所得聚合物为聚丙烯酰胺(PAM)。

| Abstract: | Photoinitiation technic was developed to polymerize acrylamide in an inverse microemulsion system by choosing the right light initiator. Using Span80+OP-10as a blend emulsifier, the inverse microemulsion polymerization of acrylamide in white oil could be completed by UV light radiation, and the molecular weight of the produced polymer was as high as 106. The effects of the type and concentration of photo-initiator, monomer concentration, emulsifier concentration and polymerization time were investigated, and a relatively good condition for polymerization of AM by UV radiation was acquired. The polymer was identified as PAM by IR spectrum. |
