Abstract The synthesis and polymerization of a new bifunctional monomer, benzenaminium 4-styrenesulfonate, containing a vinyl and an anilinium group are reported. The vinyl group was polymerized via conventional free radical polymerization to produce poly(benzenaminium 4-styrenesulfonate), while the anilinium group was polymerized via oxidative polymerization to produce polyaniline emeraldine base salt. The characterization of functional groups by spectroscopic techniques and morphology by electron microscopy indicated clear differences between both polymers. Additionally, poly(benzenaminium 4-styrenesulfonate) was found to be water soluble, while polyaniline was only water dispersible. A copolymer using acrylic acid as the co-monomer (synthesized via free radical polymerization) and a polyaniline-poly(benzenaminium 4-styrenesulfonate) system (synthesized via oxidative polymerization) were obtained to show the advantage of having functional groups that polymerize by a selective route in a single monomer unit.

通过自由基聚合和氧化途径选择性聚合新型双官能单体

摘要 报道了含有乙烯基和苯胺基团的新型双官能单体苯萘胺 4-苯乙烯磺酸盐的合成和聚合。乙烯基通过常规自由基聚合产生聚（苯胺 4-苯乙烯磺酸盐），而苯胺基通过氧化聚合产生聚苯胺翡翠碱盐。通过光谱技术和电子显微镜形态学表征官能团表明两种聚合物之间存在明显差异。此外，发现聚（苯胺 4-苯乙烯磺酸盐）是水溶性的，而聚苯胺只能是水分散性的。
