侧链含PEO链段的苯胺共聚物的合成与表征

Preparation and Characterization of a Copolymer Based on Aniline Containing PEO Segments on the Side Chain

采用化学氧化法将苯胺 (An)与间苯二氨基甲酰己二氨基甲酸聚氧乙烯乙酸酯 (MPAE)进行共聚 ,制备出一种侧链含聚氧化乙烯 (PEO)链段的苯胺共聚物。结果表明 ,MPAE投料量增加 ,共聚产率线性减少 ,共聚物的热稳定性逐渐下降 ,在极性有机溶剂中的溶解及成膜性能提高 ,但 MPAE摩尔投料量达 30 %后 ,产物溶解性无明显变化。

A copolymer containing PEO segments on the side chain was synthesized by chemical oxidation copolymerization of aniline and its derivative m-phenylene diamino formyl alkylenediamine poly(ethyleneoxy) acetate(MPAE). The results showed that the yield of the copolymers and their thermal stability declined with increasing of MPAE feed content, the solubility of the copolymers in polar organic solvents and their ability to form membrane enhanced, but further enhancement could not be observed when the ratio of MPAE to the total monomers is more than 30%.
