磺化聚苯硫醚性能研究

Studies on the Properties of Sulfonated Polyphenylene Sulfide

报道了水溶性磺化聚苯硫醚的制备方法,用红外光谱、光电子能谱和化学分析等方法对其进行结构表征,1203cm^(-1)处的强吸收峰归属于碘酸根中的S=0伸缩振动,1564cm^(-1)处的吸收峰归属于苯环骨架的伸缩振动,聚合物中的硫醚基团和碘酸根中的S_的结合能分别为162.9eV和167.7eV,碱滴定结果表明有85％的苯环被磺化,负载在活性碳上的磺化聚苯硫醚-铑配合物催化剂可催化十一烯酸甲酯的氯甲酰化反应。

The preparation method of water-soluble Sulfonated polyphenylene sulfide is described. The polymer's structure were characterized by IR XPS and chemical analysis. The sulfonat-ed polyphenylene sulfide Rhodium complexes supported on active-carbon were used as catalysts in hy-drofomylation of methyl ω-undecylenoate in organic phase system.
