摘要： 主链液晶高分子材料力学性能的各向异性,限制了其作为结构材料的应用和发展[1].含马来酸酐共聚物(如与乙烯、异丁烯、十八碳烯、苯乙烯和氯乙烯等交替、无规结构共聚物,其中马来酸酐质量分数为5%～50%)是一种耐热性和加工性优良的树脂.

Abstract: Rigid long sidechain liquid crystalline polymers with intermolecular hydrogen bonds were synthesized with random styrenmaleic anhydride copolymer(RSMA) and phydrobenzoic acid(HBA) by catalyzing and insitu acetylation. Their chemical structures were characterized by FTIR spectrum. Polarizing microscope with hotstage and DSC were applied to investigate the liquid crystallinity. It was found that RSMA-g-HBA copolymers contain intermolecular hydrogen bonds and exhibit nematic mesophase.

Key words: Rigid long sidechain liquid crystalline polymers, Intermolecular hydrogen bonds, Nematic mesophase
