| 摘 要： | 以季戊四醇为支化剂,并与硝酸铈铵组成氧化还原引发体系,在水溶液中引发丙烯酰胺（AM）和季铵型阳离子单体甲基丙烯酰氧乙基三甲基氯化铵（DMC）进行自由基共聚,合成了星形结构的阳离子聚丙烯酰胺（S-CPAM）。研究了引发剂用量、反应体系单体浓度、阳离子单体比例、聚合反应温度及反应时间等对共聚反应的影响,得出了合成S-CPAM的最佳工艺条件,并通过红外光谱对其分子结构进行了表征。 |

| Abstract: | Star-shaped cationic polyacrylamide （S-CPAM） was synthesized via free-radical solution polymerization based on acrylamide （AM） and methacryloyloxyethyltrimethyl ammonium chloride （DMC）.The co-polymerization of AM and DMC was conducted by using pentaerythritol （PETL） as the core molecule and ceric ammonium nitrate （Ce4＋） as the initiator.The effects of initiator dosage,monomer concentration,molar ratio of DMC to AM,polymerization temperature,and reaction time on polymerization were studied,and the optimum process conditions for S-CPAM were obtained.The structures of the resulting products were characterized by FT-IR,and intrinsic viscosity measurement. |
| Keywords: | star-shaped cationic polyacrylamide （S-CPAM） pentaerythritol （PETL） free-radical polymerization |
