In order to partially substitute the phenol and formaldehyde, aluminum, calcium and iron lignosulfonates, were used in the synthesis of phenol-formaldehyde resins. Metal complexed lignosulfonates have also been used as reactive comonomers in the polycondensation reaction because they possess a reactive chemical potential, put into evidence by the presence in their structure of some functional groups like: phenolic and alcoholic hydroxyl, carbonyl, carboxyl, sulfonic.
