ABSTRACT OF THE DISCLOSURE A carbohydrate-phenolic resin and a process for production of same wherein an aldose saccharide, preferably a hexose, is reacted with a phenolic compound and urea in the presence of an acid catalyst to form a resin which is curable with amine crosslinking agents, such as hexamethylenetetramine. Instead of urea, use can also be made of diamines, such as toluene diamines and alkylene diamines. The resin formed may be a solid fusible resin or a liquid resin; when a liquid resin is formed it may be reacted with a lower aliphatic alde- hyde in the presence of a basic catalyst to form a resol resin.
