摘要

An improved adhesive binder composition is provided for the preparation of lignocellulosic composite molded articles such as flake or particleboard, made from moldable compositions which comprises an organic di- or polyisocyanate and a cyclic alkylene ester of carbonic acid and optionally lignin, for application to the lignocellulosic material prior to the molding process to form the composite product.
