heal.abstract Novalac resin (N) with hexamethylenetetramine (HTA) was cured with biomass (B) or Kraft lignin (KL) or hydroxymethylated Kraft lignin (KLH) or cellulose (GEL). The agricultural/industrial by-product of olive stones was used as biomass. Kraft lignin, hydroxymethylated Kraft lignin and cellulose were isolated from the biomass. The cure was followed by DSC and IR spectroscopy. Based on the IR spectra of cured materials and their characteristic bands, the proportion of N/B = 50/50 was chosen for the preparation of novolac mixtures with other components. Only N-KLH exhibited values of Delta H higher than Delta H-m, calculated from the law of mixtures, indicating that KLH participates in the cure reaction. The kinetic parameters E and k(0) of the total cure reactions, calculated by DSC scans, increased in the order N < N-KLH < N-B < N-KL < N-CEL. The incorporation of KLH in the mass of N-HTA led to a slight increase in E and k(0). On the other hand, KL, CEL and B acted as diluents in the mass of novolac. Generally, the cure of all materials was a first order reaction, indicating that the cure mechanism of novolac remains the same. en
