摘　　要：PrCl3与漆酚经热聚合制成漆酚镨聚合物(PUPr)。PUPr用于催化邻苯二甲酸二丁酯等酯类的合成,考察了催化剂的催化活性。在一定催化条件下,产率高达84.2%。催化剂活性高,稳定性好,易于回收。Urushiol praseodymium polymer(PUPr) was prepared by hot polymerization from PrCl_3 and urushiol . The catalytic activity of (PUPr) was studied in syntheses of dibutyl (o-) phthalate etc.The result showed that the PUPr gave yield of 84.2% at optimum conditions and kept high activity and reusability.
