摘要： This invention relates to a resin made from an aldehyde component which comprises 5-hydroxymethyl furfural, and a reactive aromatic compound which comprises lignin, characterised in that the aldehyde component comprises monomeric 5-hydroxymethyl furfural, and optionally, oligomers of HMF wherein the mass fraction of oligomers in the HMF is not more than 1 %, based on the sum of masses of the HMF monomer and the masses of the HMF oligomers present in the said mixture, and methods of use of these resins as binders and adhesives for inorganic and organic materials including wood, engineered wood, paper, cardboard, stone, concrete, plaster, thermoplastic and duroplastic polymers, metals, textiles, fibres including also carbon fibres, nonwovens, felts, leather, ceramics, and glass.
