| 摘 要： | 合成了甲基丙烯酸聚氧乙烯酯大分子单体,其中含有少量双端酯化的单体。大分子单体经热交联,形成交联网络型聚氧乙烯,其与硫氰化钠形成的络合物的室温电导率较同类线型聚合物高二个数量级以上(～10-5Ω-1cm-1/298K)。红外光谱表明:交联网络含较高的非晶成份。不同络合溶剂对形成的络合物聚集态有明显影响;络合盐浓度也对络合物结晶性有影响。

| Abstract: | Some ethoxy polyethylene glycol monomethacrylate macromers containing small amount of dimethacrylate were synthesized by "Macromonomer Technique". They crosslinked on heating and polyethylene oxide networks were obtained. The complexes of the networks with sodium thiocyanate had a higher conductivity than that of corresconding linear polyethylene oxides by two orders (10-5Ω-1cm-1/298K). IR spectra of the network systems showed strong signals of amorphous construction. Effects of solvents and salt concentration on the crystallinity of the complexes were observed. can be obtained. By selecting suitable solvent and salt concentration high amorphous complexes with the highest conductivity and good hot-press processibility |
