摘要： Novel macrocyclic oligomers were synthesized through the condensation of phenolphthalein and m-phthaloyl-dichloride with triethylamine as catalyst in the mixed solution of methylene chloride and THF via pseudo-high-dilution technique. The oligomers were characterized by IR, 1H NMR, MS, WAXD, TGA and DSC. It was found that the 3∶3 adduct(molar ratio of phenolphthalein to m-phthaloyl-dichloride) and the 4∶4 adduct were the main products and there was a small amount of crystalline in the macrocyclic mixtures. When the mixtures were heated to 360 ℃, the crystalline disappeared.

关键词: macrocyclic oligomer, pseudo-high dilution technique, polycondensation, ring-opening polymerization, thermal behavior.
