摘　　要：采用光引发聚合技术进行聚丙烯酰胺(PAM)的合成。选取合适的光引发剂并进行了改性,同时研究了光引发合成PAM的影响因素。在紫外光照射下,采用改性的商品光引发剂,用量为丙烯酰胺(AM)的0.01%～0.05%,聚合单体浓度w(AM)为15%～25%,聚合时间50～90min,可获得特性粘数η=800～1400mL/g,AM残留量<0.05%的高纯聚丙烯酰胺。Photoinitiation method for Polyacrylamide (PAM) synthesis was presented . Various photoinitiators for polymerization of acrylamide(AM) were chose and modified. The feasibility and optimum conditions of this method were studied. Under the conditions that the amount of modified commercialized photoinitiator is 0.01%~0.05% (based on amount of AM), concentration of AM monomer is 15%~25%, 50 ~ 90 min of photoplymerization time, the polymer intrinsic viscosity(η) is 800～1 400 mL/g, the residual AM monomer is less than 0.05%. High purity PAM is then obtained.
