反相乳液法制备水溶性高分子引发剂的选择

Selection of Redox Initiator for Preparing Water-soluble Polymer by Inverse Emulsion Method

分别用 KPS—TMEDA、KPS—DMAEMA、KPS—NaHSO_3—DMAEMA 和 KPS—TMEDA—DMAEMA 氧化还原引发体系作制备水溶性高分子的引发剂,试验发现 KPS—TMEDA 和 KPS—TMEDA—DMAEMA 氧化还原引发体系在反相乳液中引发效果较好,并对4种引发体系的引发机理进行了探讨,试验研究了引发剂用量对聚合反应的影响。

The redox initiators such as KPS - TMEDA, KPS - DMAEMA, KPS - NaHSO3 - DMAEMA, and KPS - TMEDA - DMAEMA for preparing water - soluble polymer were studied. The test results showed that KPS - DMAEMA and KPS - TMEDA - DMAEMA behaved better for synthesizing water - soluble polymer in inverse emulsion, and the initiation mechanisms of 4 types of the above redox systems were discussed, and the effect of the amount of redox initiator on polymerization was examined.
