Abstract

Mixed novolac-type oligomers are synthesized in the melt on the base of oxibenzene and its alkilsubstituted. The content of dioxibenzene changes in the range of 0,1 – 0,5 mol. The influence of temperature and duration of the reaction of initial components, transformation has been studied.
