摘　　要：首先采用二烯丙基二甲基氯化铵与丙烯酰胺反应,制备了聚二烯丙基二甲基氯化铵-丙烯酰胺(P1),P1再与乙二醛(GL)进行反应,制备了P1-GL合成鞣剂。通过红外光谱(FT-IR)、核磁共振(1HNMR)分别对P1和P1-GL进行了表征。FT-IR和1HNMR结果表明:乙二醛与P1成功发生了反应。对P1-GL合成鞣剂进行提纯,提纯前后的P1-GL合成鞣剂分别应用于羊皮服装革预鞣,再用2%的铬粉鞣制。试验结果表明:采用未提纯P1-GL合成鞣剂预鞣,再用2%铬粉鞣制后,革样收缩温度最高可达92℃,增厚率可达70.94%;与单独使用2%铬粉鞣制工艺相比,采用未提纯P1-GL合成鞣剂预鞣革样的耐湿热稳定性、抗张强度、撕裂强度均有较大幅度提高。Polymer diallyldimethyl - ammonium chloride - acrylamide （ P1 ） was prepared by the way of free - radical polymeri- zation. Polymer diallyldimethyl - ammonium chloride - glyoxal （ P1 - GL） was prepared by using P1 and glyoxal. P1 was characterized by FT - IR and ^1HNMR, It shows that glyoxal has reacted with P1 successfully. P1 - GL was purified , and purified and unpurified polymer P1 - GL associated with 2% chromate tannage were applied in leather making process. The application results show that ：the shrinkage temperature of leather tanned by unpurified polymer P1 - GL associated with 2% chromate tannage could be 92℃, and the thickness increases more than 70, 94%, The tensile strength and humidity and thermal stability, as well as the tearing strength were better than those of tanned by chromate tannage.
