以苯乙烯、4-乙烯基吡啶、丙烯酰胺、DMC为单体,采用溶液自由基引发聚合反应,合成了3种水溶性良好,具有不同疏水端、相同亲水端的阳离子高分子分散剂。用FTIR、NMR对结构进行了表征,并测定了特性粘数与阳离子单体含量。
Using styrene, 4-vinylpyridine, acrylamide and DMC as raw materials, a family of dispersants with different anchors was synthesized by solution radical polymerization. FTIR and NMR analysis were used to characterize the polymer structures, the intrinsic viscosity and the percent of hydrophilic moieties were also studied.
