Efficient synthesis and facile polymerization of some cyclic bisphenol o-phthalates
A series of new macrocyclic aromatic esters have been efficiently synthesized from o-phthaloyl dichloride and various bisphenols, and unambiguously characterized by a combination of GPC, MS(FAB), FTIR and NMR. These macrocyclic oligomers undergo facile ring-opening polymerization in the presence of anionic initiators to give high molecular weight polyarylates.
