Abstract
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 solid fusible resin which is curable with cross linking agents, such as hexamethylenetetramine. Instead of urea, use can also be made of diamines, such as toluene diamines and alkylene diamines.
