摘　　要：以含有季铵盐和羧基的聚合物为基体,通过水溶液聚合法引入不同单体,考察单体种类对季铵盐羧酸型复鞣固色剂性能的影响。红外光谱(FT-IR)结果表明,不饱和单体成功发生了聚合;X射线衍射(XRD)结果表明,与聚合物基体相比,不同单体的引入均降低了复鞣固色剂的结晶度,提高了高分子链的柔软性;将其应用于绵羊皮服装革的复鞣工序,结果表明,在聚合物基体中引入丙烯酸-2-羟乙酯(HEA)后,坯革的K/S值达到了16.461,耐干湿擦牢度和物理机械性能良好。Retanning and fixing agents were synthesized by aqueous solution polymerization based on polymer containing quaternary ammonium salts and carboxyl groups. The effect of monomer types on properties of retanning and fixing agents was investigated. Fourier transform infrared spectroscopy （FT-IR） results demonstrated that unsaturated monomers have polymerized successfully. The results of X-ray diffraction（XRD）showed that the crystallinity of retanning fixing agents was decreased compared with polymeric matrix due to the introducing of different monomers, and then the softness of polymer chain was improved. Retanning and fixing agents were applied in retanning process of garment-leather of sheep. The application results showed that the addition of acrylic-2 hydroxyl ethyl ester （HEA） could endow resultant leather with good the dry and wet rub fastnesses, and the K/S value of the leather has reached to 16. 461. Meanwhile, the mechanical properties of leather retanned with retanning and fixing agents have improved.
