A new method of synthesis of high-molecular-weight epoxy resin (HMWER) with desired epoxy-groups content, according to so-called advancement" process was described. It is based on polyaddition of 4,4'-Isopropylidenediphenol (BPA) to a low-molecular-weight epoxy resin (LMWER) under microwave irradiation or conventional heating in the presence of catalyst. Microwave syntheses were carried out in a multi-mode reactor "Plazmatronika" (Poland) of microwave frequency 2.45GHz and maximal microwave power 300W. Analogical syntheses provided under conventional heating have been done for comparison of the methods. The results showed, that in tested group of catalysts shortening of the reaction time (for process conducted under microwave irradiation in comparison to conventional heating) is possible only for 2-methylimidazole.
