The invention relates to processes for the manufacture of thermally curable resins containing the step of the reaction of a polycondensation-capable phenolic compound and/or of an aminoplastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to formation of polycondensation products and is characterized in that the HMF comprises at least one HMF oligomer. The invention further relates to thermally curable resins and to the use of the resins for the manufacture of a wood composite material.
