中文摘要 | phenolphthalein based polyarylate macrocyclic oligomers were selectively synthesized by an interfacial polycondensation reaction of o-phthaloyl dichloride with phenolphthalein. the high selectivity benefits from the role of phenolphthalein as a color indicator, an efficient phase transfer catalyst, acid a preferred conformation of the starting materials as indicated by analyzing a single-crystal x-ray structure of an analogous macrocycle. the melt rop of phenolphthalein polyarylate cyclic dimer was studied using nucleophilic initiators, the molecular weight of the resulting polymers builds up very rapidly at the very early stage of polymerization but decreases with time. during the rop of cyclic dimer, analogous macrocycles with higher degree of polymerization (n greater than or equal to 3) and linear oligomers were produced by backbiting reaction especially at later stage of polymerization. conversion of cyclic dimer is very fast at the earlier stage of polymerization and then increases slowly with time as analyzed by gel permeation chromatography. however, the total amount of cyclic oligomers in the rop system increases with time at the later stage of polymerization because of the formation of larger macrocycles. the resulting polymers are amorphous. glass transition temperatures (t(g)s) of these polymers are influenced by the polymerization time, type of initiator, and initiator concentration. |
