Processes for the manufacture of thermally curable resins contain 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. The HMF includes at least one HMF oligomer. Further, thermally curable resins produced by such processes may be used for the manufacture of a wood composite material. La invención se relaciona con un método para la producción de resinas de fenol termocurables conteniendo la etapa de la transformación de un compuestos fenólico susceptible de policondensación, con 5-hidroximetilfurfural (HMF) bajo condiciones que inducen la formación de productos de policondensación y se caracteriza porque el HMF comprende al menos un oligómero de HMF y la etapa de transformación se realiza con valores pH arriba de 7 durante más de 60 minutos. La invención se relaciona además con resinas termocurables y con el uso de las resinas de fenol para la producción de una materia compuesta de madera.
