Method for producing a composition which comprises forming an aqueous Binder composition with reactive components including Molecules of lignin and cook the composition between 45 and 95 to polymerize The Adhesive Binder composition; components; composition; and use of both

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.
