Dendrimeric and hyperbranched polymers - Additives for wood glues and foams

Dendrimeric and hyperbranched polymers are multi-branched, "tree-like" chemical entities which, thanks to their end groups, enable applications in a variety of fields. Each polymer can exhibit different properties depending on the nature of the chemical compounds used, each compound being responsible for determining the type of repeating units, branching... As a result, all these parameters can induce remarkable distinctions in terms of solubility, polarity and overall reactivity. The incorporation of such entities into a polymer system is generally intended to induce curing and improve rheological properties, or to confer improved adhesion. In addition to well-known applications in the biomedical field, this article presents new prospects for the use of dendritic and hyperbranched polymers to improve wood adhesives and develop foams.
