Procedimiento para producir polímeros análogos a resinas de fenol-formaldehído

Procedimiento para la producción de polímeros análogos a resinas de fenol-formaldehído, en donde un componente fenólico se hace reaccionar con formaldehído, caracterizado en que el componente fenólico de la resina se sustituye por lignina desde el 60% al 100%, preferiblemente desde el 80% al 100% y...

Beschreibung
Zusammenfassung:	Procedimiento para la producción de polímeros análogos a resinas de fenol-formaldehído, en donde un componente fenólico se hace reaccionar con formaldehído, caracterizado en que el componente fenólico de la resina se sustituye por lignina desde el 60% al 100%, preferiblemente desde el 80% al 100% y en que la cantidad de formaldehído representa más del 0% en peso, pero como máximo el 5% en peso relativo a la masa total de materiales de partida aromáticos. The invention relates to a method for producing phenol formaldehyde resin-based polymers, wherein a phenolic component is reacted with formaldehyde, wherein 60% to 100% of the phenolic component of the resin is replaced by a lignin, and wherein the quantity of formaldehyde is more than 0% by weight, but no more than 5% by weight relative to the total mass of aromatic raw materials. The invention further relates to PF-based resins which can be produced according to such a method and also to materials which can be produced from such PF-based resins.
