漆酚-醛类缩聚物与三氯化镨的配合反应研究

Abstract

Abstract: 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 Pr³⁺. The coordinated product possessed better heat resistance, having 5%-20% less weight loss at 460℃ than the corresponding polymer.

Key words: urushiol, aldehyde, PrCl₃, coordination reaction

CLC Number:

TQ433
