摘　　要：以甲基丙烯酸β-羟乙酯(HEMA)为第二单体,与甲基丙烯酸正丁酯(BMA)悬浮聚合制得BMA/HEMA二元共聚物,采用冻胶纺丝法制备BMA/HEMA共聚纤维,研究了加入HEMA的对纤维结构与性能的影响。结果表明:随着HEMA含量的增加,BMA/HEMA纤维分子间氢键作用和物理交联作用增强,纤维的玻璃化转变温度升高,但纤维表面变得粗糙,具有疏松多孔结构,其吸附性能提高。当HEMA质量分数为15%时,BMA/HEMA纤维对有机液体三氯乙烯的吸附量达18.5g/g。A binary copolymer of butyl methacrylate （BMA） andβ-hydroxyl ethyl methacrylate （HEMA） was prepared from BMA and HEMA as the second monomer via suspension polymerization, from which BMA/HEMA copolymer fiber was prepared via gel spinning process. The effect of the addition of HEMA on the structure and properties of the fiber was studied. The results showed that the hydrogen bend interaction and physical crosslinking reaction were enhanced between the BMA/HEMA fiber molecules, the glass transition temperature was elevated, and the adsorption property was improved due to the formation of the rough surface and the loose and porous structure as the HEMA content was increased. The adsorption capacity of BMA/HEMA fiber reached 18.5 g/g for the organic liquid of trichloroethylene as the mass fraction of HEMA was 15%.
