The kinetics of the cure reaction for a system of bisphenol-S epoxy resin (BPSER), with 4,4Π-diaminodiphenylmethane (DDM) as a curing agent, were studied by means of differential scanning calorimetry (DSC). Analysis of DSC data indicated that an autocatalytic behavior showed in the first stages of t
## Abstract Bisphenol A novolacs were synthesized in both melting and solution processes using __p__βformaldehyde and formalin solution in presence of oxalic acid catalyst, respectively. Hydrogen nuclear magnetic resonance, ^1^H NMR, investigations show a high methylene bridge contents in the novol
