摘　　要：为了对聚甲基丙烯酸甲酯(PMMA)进行吸附改性,选用具有较长侧链的甲基丙烯酸月桂酯(LMA)以及带有刚性部分的苯乙烯(St)作为共聚单体,制备了聚甲基丙烯酸月桂酯-甲基丙烯酸甲酯(二元树脂)和聚甲基丙烯酸月桂酯-甲基丙烯酸甲酯-苯乙烯(三元树脂)纤维,实验结果显示单体完成共聚反应,二元树脂接触角为116.2°,苯乙烯的加入提高了三元树脂的疏水性,其接触角为134.2°。In order to modify the adsorption of polymethyl methacrylate(PMMA),the lauryl methacrylate(LMA)with long side chain and styrene(St)with rigid part are used as comonomer to prepare poly(lauryl methacrylate-co-methyl methacrylate)(binary resin)and poly(lauryl methacrylate-co-methyl methacrylate-co-styrene)(ternary resin)fibers.The experimental results show that the monomer have completed the copolymerization,the contact angle of binary resin is 116.2°,the addition of styrene improves the hydrophobicity of the ternary resin,and its contact angle is 134.2°.
