METHOD FOR PRODUCING PHENOL FORMALDEHYDE RESIN-BASED POLYMERS

摘要

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.
