中文摘要:
      本文通过后期磺化、溴化反应及溴与三甲基胺(或二甲基胺)发生取代反应而获得聚两性电解质——季铵化聚苯硫醚(聚合物4)和叔铵化聚苯硫醚(聚合物5)。用酸碱滴定和莫尔法分别测定磺化度和溴化度,并利用红外光谱、紫外-可见光谱表征了合成产物的结构。结果表明:在最佳磺化条件下.即反应时间4h、反应温度1050C、PPS与发烟硫酸比1:15(g/mL),相应的磺化度为47.6%;在最佳溴化条件下,即反应时间4h、反应温度4JD℃、FeC]3加量4%,相应的溴化度为28.20%;聚两性电解质分子链上的季铵基团和叔铵基团取代了溴。由红外光谱和紫外-可见光谱分析结果可以推定,本文对聚苯硫醚的改性是成功的,即最终合成了两性聚苯硫醚。图2表2参24
英文摘要:
      The polyampholyte,ampholytic polyphenylene sulfide were prepared via sulfonation reaction,bromination reaction and substitution reaction between bromide and quaternary ammonium group or tertiary amine group.The degree of sulfonation and the contents of bromide were investigated by acid base titration and Mohr method,respectively,and the structure of these polymers was characterized by IR and UV-vis measurement.The results indicated that sulfonation degree of polyphenylene sulfide could be up to 47.6% under the best conditions,i.e.,the ratio of oleum to PPS was 1∶ 15(g/mL),reaction temperature was 105℃ and reaction time was 4 h.The content of bromide was 28.20% when the dosage of FeCl3 was 4%,the reaction time was 4 h,and the reaction temperature was 40℃.Bromine on the benzene ring was substituted by quaternary ammonium group and tertiary amine group.Through analysis of IR and UV-vis spectrum,it could be speculated that the modification of polyphenylene sulfide was successful and the polyampholyte was obtained.
