Effect of soft segment molecular weight and NCO:OH ratio on thermomechanical properties of lignin-based thermoplastic polyurethane adhesive

[Display omitted] •Lignin-based thermoformable polyurethanes (LTPUs) were synthesized.•The interplay between synthesis parameters was investigated.•LTPUs were applied as hot melt adhesives for wood bonding. During the last decades lignin has been largely applied on development of reactive polyuretha...
