摘　　要：用动态机械热分析、红外光谱、荧光光谱、热重分析等研究漆酚-醛类缩聚物与三氯化镨的反应情况。结果表明，利用热聚合方法合成的漆酚-醛类高聚物PUX1～PUX6，常温下均能与PrCl，发生化学反应。高聚物与PrCl3不是简单的物理掺杂，而是化学反应，形成了新的化学键，氧原子是Pr^3＋最好的配体；配合产物具有更好的耐热性，在失重最快处460℃时的失重比其相对应的高聚物减少了5％～20％。Coordination reactions of different urushiol-aldehyde condensated polymers （PUX1-PUX6 ） with PrCl3 were studied by DMTA, IR, fluorescence spectrophotometry, TG, etc. Results showed that all these polymers could react with PrCl3 in different degrees under room temperature. PUX1-PUX6 with PrCl3 were not blended physically but reacted chemically to form new chemical bonds. Oxygen was the best ligand of Pr^3＋ . The coordinated product possessed better heat resistance, having 5 % -20 % less weight loss at 460 ℃ than the corresponding polymer.
