Abstract

A novel method of synthesis of unsaturated polyester (UP) resins, based on the catalytic (i.e., with lithium chloride) copolymerization of alkylene oxides (i.e., epichlorohydrin) with acid anhydrides (i.e., maleic, phthalic ones) under microwave irradiation is described. In comparison with condensations of acid anhydrides with diols, this reaction proceeds without emission of any volatile product. All the syntheses were performed under both either conventional heating or microwave irradiation (two variants: mono- and multimode). In general, the application of microwave irradiation allows to reduce the reaction time.
