中文摘要：

以AA（丙烯酸）、Al（铝）和XG（黄原胶）为主要原料，采用水溶液聚合和配位反应法制备了PAA（聚丙烯酸）／Al／XG复合材料，并对PAA／Al、PAA／Al／XG两种复合材料的结构与性能进行了对比试验。结果表明：PAA／A1复合材料和PAA／Al／XG复合材料均具有良好的鞣制性能（两者的拉伸强度分别为12．96、24．52MPa，断裂伸长率分别为73．30％、84．66％，撕裂强度分别为43．43、88．05MPa），但后者的鞣制性能、热稳定性能和其他应用性能相对更好。

英文摘要：

With AA（acrylic acid） ,Al（aluminum） and XG（xanthan gum） as main raw materials,a PAA（polyacrylic acid）/Al/XG composite was prepared by aqueous solution polymerization and complexation,and the contrast experiments between PAA/Al composite and PAA/Al/XG composite were implemented in structures and properties. The results showed that the PAA/Al composite and PAA/Al/XG composite had all good tanning properties （both tensile strengths were 12.96 MPa and 24.52 MPa respectively,elongations at break were 73.30% and 84.66% respectively,tearing strengths were 43.43 MPa and 88.05 MPa respectively）,but the tanning properties,thermal stability and other applications properties of the latter were reversely better.
