“…Although the acid conditions required for the polymerization of the furanic polymers may degrade the wood stability [ 43 , 44 ], some interesting methods to neutralize the conditions post-curing were proposed [ 45 , 46 ] and therefore, the furanic/phenolic copolymers were also preliminarily tested as wood adhesives for wood-to-wood bonding and particleboard production to observe whether or not these polymers present promising physical properties for replacing the existing adhesives.…”

Furfuryl alcohol is a very interesting green molecule used in the production of biopolymers. In the present paper, the copolymerization in acid environment with natural, easily-available, phenolic derivatives is investigated. The processes of polymerization of the furfuryl alcohol with: (i) spent-liquor from the pulping industry and (ii) commercial tannin from acacia mimosa were investigated though viscometry and IR-spectroscopy. The curing kinetics of the formulations highlighted the importance of the amount of furfuryl alcohol and catalyst as well as the effect of temperature for both phenolic-furanic polymers. Evidence of covalent copolymerization has been observed through infrared spectrometry (FT-IR) combined with principal component analysis (PCA) and confirmed with additional solubility tests. These bio-based formulations were applied as adhesives for solid wood and particleboards with interesting results: at 180 • C, the spent-liquor furanic formulations allow wood bonding slightly with lower performance than PVA in dry conditions, while mixed formulations allow the gluing of particleboard with only satisfactory internal bonding tests.

“…In Kapitel 4. Der Grund für die Annahme lag darin begründet, dass der äußerst dünne Klebefilm zu unzureichenden Klebstoffbenetzung aufgrund der rauen Oberflächenstruktur führen könnte, während PVAc-Leime wegen ihrer Beschaffenheit ein s. g. Fugenfüllvermögen besitzen (Dunky 2002a).…”
