| 中文摘要 | a series of macrocyclic aryl ketone oligomers were prepared by the reaction of phthaloyl dichloride or isophthaloyl dichloride with various bridge-linking electron-rich aromatic hydrocarbons 3a-d under pseudo-high dilution conditions in the presence of lewis base via friedel-crafts acylation reaction. detailed structural characterization of these oligomers confirmed the cyclic nature by a combination of maldi-tof-ms, gpc, and h-1 nmr analyses. these cyclic ketone oligomers have high solubility in organic solvents and the cyclic oligomers derived from phthaloyl dichloride are amorphous. the cyclic ketone oligomers readily undergo anionic ring-opening polymerization in the melt by using potassium 4,4'-biphenoxide as the initiator, producing linear, high molecular weight poly(ether ketone)s. moreover, the isothermal chemorheology of the ring-opening polymerization of cyclic oligomers 4a and 4b was also investigated. the results show that the shear viscosity of the molten reactive mixture is lower than 10 pa at a constant shear rate of 0.05 rad/sec and increases slowly in the initial stage of ring-opening polymerization. copyright (c) 2009 john wiley & sons, ltd. |
