摘要：2,4,6-Tri(4-propargyloxy-phenyl)pyridine(POPP) was made from 2,4,6-tri (4-hydroxyphenyl)pyridine(HPP) and propargyl bromide. The chemical structures of POPP and HPP were well characterized by means of FTIR, H-1-NMR, C-13-NMR, and elemental analysis. Novel polytriazole resins (P-PTA resins) were prepared from POPP and azide compounds via 1, 3-dipolar cycloaddition reaction and characterized by solubility, FTIR, DSC, and TGA analyses. The P-PTA resins show good solubility in common solvents. The resins could be cured at 80 degrees C. The glass transition temperature (T-g) and the 5% weight loss temperature (T-d5) of the cured P-PTA-33 resin arrive at 310 and 365 degrees C in nitrogen atmosphere, respectively.
