Metodo para producir una composicion aglutinante que comprende formar una composicion acuosa con componentes reactivos incluyendo moleculas de lignina y cocer la composicion entre 45-95°c para polimerizar los componentes; composicion aglutinante; composicion adhesiva; y uso de ambas

摘要

The present invention relates to a method for producing a binder composition, wherein the method comprises the following steps: (i) forming an aqueous composition comprising reactant components including lignin molecules of 11-60 lignin units, lignin molecules of 1-10 lignin units, polymerizable substance and crosslinking agent in the presence of a catalyst; and (ii) cooking the composition at a temperature of 60-95° C. for polymerizing the reactant components until a binder composition with a predetermined viscosity value is formed.
