ABSTRACT = {Bisphenol-C epoxy crotonate resin was synthesized by reacting 8.09g epoxy resin of bisphenolC, and 2.15g crotonic acid using 25 mL 1,4-dioxane as a solvent, and 1 mL triethylamine as a
catalyst at reflux temperature for 1-6 h. Solid epoxy crotonate (ECCR) is highly soluble in
common organic solvents. ECCR was characterized by its acid (24.5-1.5 mg KOH/g) and hydroxyl
(504.5-678.4 mg KOH/g) values. The structure of ECCR is supported by FTIR and 1
HNMR
spectroscopic methods. A DSC endothermic transition at 229o
C indicated melting followed by
thermal polymerization of ECCR. ECCR is thermally stable up to 320o
C and follows three-step
degradation kinetics. The first step followed first-order degradation kinetics, while the second
and third steps followed one-half-order degradation kinetics. High values of kinetic parameters
suggested the rigid nature of the crosslinked resin. Jute-, Glass- and Jute-natural fiber-ECCR
composites showed moderate tensile strength, flexural strength, electric strength, and volume
resistivity due to the rigid nature and poor interfacial adhesion of the composites. J-ECCR and
G-ECCR composites showed high water absorption tendency and excellent hydrolytic stability
against water, 10% aq. HCl and 10% aq. NaCl and even in boiling water. Mechanical and
electrical properties and water absorption tendency of the composites indicated their usefulness
as low load-bearing housing and insulating materials. They can also be utilized in harsh
environmental conditions.},
