<p>Carbohydrate-phenolic resol resins are produced in a process in which a phenolic compound is reacted with a carbohydrate in the presence of a basic catalyst to form a resin intermediate in a first stage, and then, in a second stage, the resin intermediate is reacted with a lower aliphatic aldehyde in the presence of a basic catalyst to form the resol resin. The resins produced in the practice of this invention are particularly well suited for laminating and adhesive applications.</p> |
