以４－苯乙烯基吡啶（４ＳＺ）为质子受体，侧链含苯甲酸的苯乙烯／马来酸单酯共聚物（ＭＥ－ＳＭＡ）为质子供体，四氢呋喃为溶剂，制备高分子氢键复合物。ＤＳＣ和ＰＯＭ的结果表明该氢键复合物在１４６～２０４℃呈现向列相液晶态。ＩＲ结果证实了羧基和吡啶环的分子间氢键代替了羧基间的分子间氢键。
Using 4-styrylpyridine (4SZ) as proton acceptor, side-chain styrene / maleic acid monoester copolymer containing benzoic acid (ME-SMA) as proton donor and tetrahydrofuran as solvent, Complex. DSC and POM results show that the hydrogen bonding complex exhibits nematic liquid crystal state at 146 ~ 204 ℃. The IR results confirm that the intermolecular hydrogen bonds of the carboxyl group and the pyridine ring replace the intermolecular hydrogen bonds between the carboxyl groups.
