Abstract The epoxymethcrylate resin (EMBHBCMA) of (2E, 6E)-bis(4-hydroxybenzylidene)-4-
methylcyclohexanone(EMBHBC) was synthesized by condensing EMBHBC and methacrylic
acid (1:2 mole ratio) by using 1,4-dioxane as a solvent and triethylamine as a catalyst at reflux
temperature for 1-5 h to get acid value < 10. The structure of EMBHBCMA was supported by
UV-Vis, FTIR, 1
HNMR and 13CNMR spectroscopic techniques. Molecular weights and molecular
weight distribution of EMBHBCMA were determined by gel permeation chromatography.
EMBHBCMA is thermally stable up to about 300°C and followed two step degradation reactions.
Kinetic parameters such as n, Ea, A and ΔS* were determined according to Anderson-Freeman
method… More >
