TL;DR: In this paper, a process for the production of a carbohydrate-phenolic resol resol resin is described, in which an aldose saccharide, preferably a hexose, is reacted with a phenolic compound and urea in the presence of an acid catalyst to form a liquid fusible resin which is then react with a lower aliphatic aldehyde and a basic catalyst.
