Synthesis, Characterization and Ring-Opening Polymerization of Macrocyclic Aryl Ketone Oligomers Containing the Phthaloyl Moiety

Abstract:

Preparation of macrocyclic aryl ketone oligomers containing the phthaloyl moiety by Friedel-Crafts acylation reaction is described. Detailed structural characterization of these oligomers confirmed the cyclic nature by a combination of MALDI-TOF-MS and GPC analyses. The cyclic aryl ketone oligomers are amorphous and 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 with excellent thermal stability.
