ABSTRACT = {The epoxy methacrylate of (2E,6E)-2, 6-bis(4-hydroxybenzylidene)cyclohexanone (EBHBCMA)
was synthesized by condensing 0.02 equi. EBHBC, 0.04 equi. methacrylic acid, 50 mL THF
as a solvent and 0.2 mL triethylamine as a catalyst at reflux temperature for 1-5 h to get acid
value < 10. EBHBCMA showed good solubility in common solvents. The structure of
EBHBCMA was supported by UV-Vis., FTIR, 1
H NMR, and 13C NMR spectroscopic techniques.
DSC thermogram of EBHBCMA exhibited two endothermic peaks (86.4 and 117.1 °C) and
one exothermic peak (142.6°C) due to moisture release, melting and curing of the resin,
respectively. EBHBCMA is thermally stable up to about 316 °C and followed single step
degradation reaction. EBHBCMA followed apparently second order (1.7) degradation kinetics
with 277.69 kJ mol<sup>-1</sup> energy of activation, 5.93 × 10<sup>18</sup> s<sup>-1</sup> frequency factor and entropy change
of 107.4 JK<sup>-1</sup>mol <sup>-1</sup>.},
