Inventia se refera la un procedeu de obtinere a unor complecsi de cobalt folositi ca agenti de aderenta pentru reteua de cord metalica în industria anvelopelor si este complementara la inventia principala, cu brevetul nr. 87996. Procedeul prevede cadupa desavarsirea reactiei dintre derivatul mono sau dimetiloic al unui alchil sau arilfenol si Co(OH)2 în prezenta de hidrocarbura aromatica si apa la temperatura de pana la 150 degree Csa se introduca un plastifiant, dupa care se distileaza solventul si apa la 100..150 degree C si la presiune reziduala de maximum 100 torr.The invention relates to a process for obtaining cobalt complexes used as adhesion agents for the metallic cord network in the tire industry and is complementary to the main invention, 87996. The process provides for the completion of the reaction between the mono or dimethyloyl derivative of an alkyl or arylphenol and Co (OH) 2 in the presence of an aromatic hydrocarbon and water at a temperature of up to 150 degrees Csa a plasticizer is introduced, after which the solvent and water at 100 ° C to 150 ° C and at a residual pressure of not more than 100 torr.
