AbstractDuring the past 15 years, increasing application of microwave heating to polycondensation reactions has been witnessed. Experiments have been carried out at laboratory scale using widely different experimental procedures. The use of microwaves has often led to significant benefits compared to conventional heating experiments in terms of multi-fold decrease in reaction times and energy consumption and production of polymers with increased molecular weight and improved mechanical properties. In other cases, microwaves do not appear to 2 produce any significant benefits compared to conventional heating. At present, guidelines to experimentalist as to the process conditions and experimental design that should be applied are missing and experimentation seems to be based on an empirical trial-and-error approach.In view of the very different experimental protocols that have been applied and the contradictory trends that are frequently reported, we aim in this review to shed light on the role of important process parameters, such as the presence and type of solvent, the dielectric properties of the mixture and the individual phases, the use of heterogeneous catalysts, pressure, stirring, reflux conditions, temperature measurement method and microwave absorbing fillers, which all seem to determine the occurrence and magnitude of the benefits enabled by microwaves during polycondensation reactions.

“…In continuation of our work related to the development of new heteroaromatic macromolecular structures, we have intended to synthesize Poly(Tetrasubstituted Aryl Imidazole)s (PTAIs) by a four-component reaction. In the frame of ongoing studies related to the beneficial effects of microwave irradiation on the synthesis of heteroaromatic polymers by polycondensation [9,10] these polymerizations were performed under microwave irradiation.…”

A novel, effi cient methodology for the synthesis of phthalonitrile derivatives was investigated, using ionic liquid (IL) and microwave media as well as both simultaneously. Phthalonitrile monomers containing imide linkages were prepared from the reaction between aromatic dianhydrides, 3,3 ′ ,4,4 ′ -benzophenonetetracarboxylic dianhydride (BPTA), pyromellitic dianhydride (PMDA), 4,4 ′ -(hexafl uroisopropylidene) diphthalic anhydride (6FDA), 3,3 ′ ,4,4 ′ -biphenyltetracarboxylic dianhydride (BTDA) and the end-capping agent 4-(3-aminophenoxy) phthalonitrile through the imidization reaction. The use of the IL1-butyl-3-methyl imidazoliumchloride as a solvent signifi cantly increased the rate and yield of the reaction. The use of microwave irradiation and reaction parameters signifi cantly shortened the reaction time while enhancing the purity. The polymerization of the prepared phthalonitrile monomers was carried out with 3 wt % of aromatic diamine 4,4 ′ -oxydianiline (ODA) curing agent under microwave irradiation. It is shown that condensation was successfully carried out using the recyclable IL medium under microwave irradiation.
