摘　　要：用一步法由三聚氯氰和均三酚在丙酮中,用K2CO3作缚酸剂合成了一种端羟基的超支化聚合物(HTHP),HTHP可作为一种铬鞣助剂应用于皮革铬鞣工序中。结果表明,HTHP对增加皮胶原对铬盐的吸收和固定有显著效果,HTHP用量为酸皮质量的1%时,铬鞣废液中的Cr2O3由未加入HTHP的1.42 g/L降低到0.60 g/L,坯革的收缩温度由90℃提高到94℃,且粒面细致。加入HTHP后,改善了坯革对染料和加脂剂的吸收,坯革表面色泽浓厚,浴液颜色浅淡清亮。A hydroxy terminated hyperbranched polymer （HTHP） was synthesized with 1,3,5- benzenetriol and cyanuryl chloride as starting materials in acetone by one step method. HTHP was used in chrome-tanning process as an assistant. The result shows that HTHP significantly improved absorption and fixation of chrome salt and dyestuff. Using 1% HTHP （based on weight of pickled leather）, Cr2O3 in chrome-tanning waste solution was reduced from 1.42 g/L to 0.60 g/L, the shrinkage temperature （ Ts ） was raised from 90 ℃ to 94 ℃ , meanwhile the grain was fine. HTHP applied in tanning process can help the absorption of dyestuff and fat-liquor. The surface of the crust is deep dark, and the effluent is transparent and clear.
