ABSTRACT:
A process for the production of a modified phenol-aldehyde resin which may form a binder system when combined with a curing agent which includes an additional source of an aldehyde, e.g., a phenol-formaldehyde resin. The inventive phenol-aldehyde resin may be modified with compounds from one of the following classes: (1) dihydroxybenzenes, (2) arninophenols, and (3) phenylenediamines. The resin and adhesive are useful in the production of a wood composite (such as plywood, oriented strandboard, or fiberboard).
