Abstract
Preparation of cyclic aryl ketone oligomers containing the iso-phthaloyl moiety by Friedel-Crafts acylation reaction is described. These cyclic oligomers are characterized by a combination of MALDI-TOF-MS and NMR analyses. The cyclic aryl ketone oligomers readily undergo anionic ring-opening polymerization in the melt by using potassium 4, 4-biphenoxide as the initiator, affording linear, high molecular weight poly (ether ketone) s with excellent thermal stability.
