In the present study, a quick method for the determination of composition of the resin formed by alkaline-catalyzed cardanol-formaldehyde reaction has been suggested. The complete analysis of the product could be carried out by determining experimentally the concentration of only one reactant, viz.,
## Abstract Novolac resins having cardanol‐to‐formaldehyde mole ratios of 1:0.4, 1:0.5, and 1:0.6 were prepared by using aromatic sulphonic acid as the catalyst at four different temperatures ranging between 90°C and 120°C, with an interval of 10°C. Free formaldehyde and free phenol contents were d
## Abstract Phenol‐modified cardanol–formaldehyde novolac resins have been synthesized using equal proportions of phenol and cardanol. To this mixture of phenol and cardanol, 0.6 and 0.8 mol of formaldehyde were added separately, under acidic conditions, at five different temperatures ranging betwe
