| 摘 要： | 我们曾经报道过硫酸盐和脂肪族六元环胺可以组成氧化还原引发体系用于烯类单体水溶液聚合,并且证实环仲胺如吗啉(MP)和哌啶(PD)被氧化后生成氮自由基参与了引发反应。本文对过硫酸盐和五元环胺吡咯烷(PyD)组成的引发体系进行了研究。 1 实验部分

| Abstract: | Kinetic study of acrylamide (AAM) polymerization was carried out with persulfate-pyrroli-dine(PyD) system as the initiator and revealed that PyD is an accelerator for acrylamide polymerization. The initial free radicals of persulfate-PyD system was studied by spin trapping technique and ESR spectrum. The result confirms that the pyrrolidinyl free radical is one of the primary free radicals responsible for AAM polymerization. |
