摘　　要：以环糊精作为为丙烯酸长链酯的增溶载体,实现了疏水单体丙烯酸十八酯、丙烯酸十二酯与亲水单体丙烯酸的三元乳液共聚,旨在提升两亲聚合物复鞣加脂剂的综合性能。通过FTIR、GPC对聚合物结构和相对分子质量等基本性能进行了表征,并考察了三元聚合物复鞣加脂效果。结果表明:成功合成了目标产物,其乳液静置稳定性好,残余单体少,产物数均相对分子质量约为4000,在皮革内能较好渗透,具有较理想的复鞣加脂效果,复鞣加脂革的柔软度高、静态防水性好,且吸收率高达98.41%,能大幅降低废液中的COD。The ternary emulsion copolymerization of two hydrophobic monomers,octadecyl acrylate and dodecyl and the hydrophilic monomer,acrylic acid was realized by using cyclodextrin as the solubilizing carrier of acrylic long chain esters,aiming at improving the comprehensive performance of the retanning and fatliquoring agent of amphiphilic polymer.The structure and molecular weight of the polymer were characterized by FTIR and GPC,the basic properties of the amphiphilic polymer emulsion were measured,and the application effects of the copolymer on retanning and fatliquor were also investigated.The results showed that the target product was successfully synthesized,and the emulsion had good stability.The number average molecular weight of the product was about 4000.It could penetrate well into the leather.The ternary copolymer had?ideal retanning and fatliquoring effect,and the treated leather had high softness,good static waterproofness.The absorption rate was up to 98.41%,which could greatly reduce COD in waste liquid.
