Replacing grafted anhydride polyolefin coupling agents with copolymers in which the anhydride is one of the reactive monomers is a recent development in wood-plastic composites. Among the benefits of this approach is that less of the coupling agent is needed, Dupont has developed a grade of Fusabond W PC 567 D on copolymer of polyolefins.
