Macrocyclic Oligoimides .1. Preparation of Macrocyclic Oligoetherimides via Kricheldorf Substitution Polymerization
Macrocyclic oligoetherimides were synthesized by means of Kricheldorf’s nucleophilic aromatic substitution polycondensation, A solution containing equimolar quantities of bis(trimethylsilyl ether) of bisphenol and arylenebis(fluorophthalimide) was continuously added into a high boiling solvent containing CsF catalyst under a pseudo-high dilution condition. The resulting reaction mixture contained a high yield of cyclic oligomers which could be isolated by solvent extraction.
