“…The next generation of cellulosic ethanol is being developed from these polysaccharides with microbial fermentation [3,4]. Lignin, a phenolic polymer, is also an important source for industrial applications such as adhesive resin [5,6] and lignin gels [7,8]. Lignin and cellulose are being developed for the synthesis of biodegradable polymers [9].…”

“…The wood panel itself is constituted of 99.5 % natural materials, the 0.5 % balance being composed of glyoxal, a non-toxic and nonvolatile aldehyde, for the preglyoxalation of lignin and of hexamine already accepted as a non-formaldehyde-yielding compound when in presence of a condensed tannin. Both particleboard and two types of plywood were shown to pass the relevant interior standards with such adhesive formulations (El Mansouri et al 2007b;Mansouri et al 2011a;Navarrete et al 2012). The mechanism of copolymerization and hardening can be understood from Fig.…”

& Key message Green chemistry for and from wood has developed numerous industrial products, namely biosourced, green wood adhesives and preservatives, foams, composite matrices, laminates, hard and flexible plastics, flexible films, and abrasive grinding discs, and their number is still growing. & Introduction This review addresses (1) the elimination of toxic aldehydes from the most common wood panel adhesive, the one based on urea, itself a natural product, (2) biosourced adhesives derived from wood or other vegetable matter and used for wood products, and (3) wood and bark tannin-based foams, natural fiber composites using tannin matrices, paper surface laminates and continuous high-pressure paper laminates using tannin-furanics, hard plastics based on tanninfuranic materials and some of their applications, flexible biosourced tannin-furanic films, and biosourced wood preservatives.

“…Glyoxalated lignin has been incorporated into PF resin, tannin, and polymethylene polyphenyl isocyanate (pMDI) to use as an adhesive in wood composites (El Mansouri et al 2007b;Navarrete et al 2012). Particleboard containing 10% of adhesive was fabricated with two formulations, which consisted of 55/20/25 glyoxalated calcium lignosulfonate/pMDI/PF proportions and 60/40 glyoxalated calcium lignosulfonate/pMDI proportions (El Mansouri et al 2007a).…”

Synthesis and Thermal Stability of Glyoxalated Alkali Lignin-Polyvinylpyrrolidone Resins

Natural, renewable, and non-toxic lignin-based resin was synthesized through copolymerization with monomeric N-vinyl-2-pyrrolidone (VP) in the presence of benzoyl peroxide (BPO) as the free radical initiator. Glyoxalated lignin was used as the feedstock. The mechanism of copolymerization between the glyoxalated alkali lignin and VP monomer was determined through Fourier-transform infrared spectroscopy (FT-IR). The optimum amount of VP monomer used and the reflux time required in the synthesis process were determined through thermogravimetric analysis (TGA). In the presence of BPO, copolymerization between glyoxalated alkali lignin and VP monomer was accomplished via the formation of ether linkages in a condensation reaction at pH 7.0. More ether linkages were formed with higher amounts of VP monomer and longer reflux times. The addition of VP monomer into glyoxalated alkali lignin increased its thermal stability. FT-IR and TGA indicated that 0.012 moles of VP monomer and an 8-h reflux time were optimum conditions for the synthesis of glyoxalated alkali lignin-polyvinylpyrrolidone resins.
