The purpose of the work is to study the process of synthesis of furfuryl oligomers with high molecular weight at various ratios of furfuryl alcohol and hydroxyl-containing polyether polyol. The influence of the process method on the yield of high-molecular furfuryl oligomer is shown - with a one-step synthesis method with an increase in the amount of furfuryl alcohol from 20 to 50 moles per 1 mole of polyether polyol, the yield of the final product decreases from 75% to 56%, apparently due to high exothermic effects, causing gelation systems. In contrast to the one-time introduction of the catalyst, its dosed introduction allows you to regulate the exothermic effect of the reaction and, thus, prevent premature gelation. Thus, with the gradual addition of a catalyst, the yield of high molecular weight furfuryl oligomer increases from 71.5 to 82.5% when the amount of furfuryl alcohol changes from 20 to 50 moles per 1 mole of polyether polyol taken for synthesis. A study of the curing of synthesized high-molecular furfuryl oligomers showed that with an increase in the molar ratio of furfuryl alcohol: polyether polyol, the yield of the gel fraction increases from 72% to 78%. Thus, the systematic studies carried out made it possible to scientifically substantiate the stepwise synthesis of high-molecular furfuryl oligomers.
