Abstract

Epoxy maleate of 9,9'-bis(4-hydroxyphenyl)anthrone-10 (EANM) was synthesized and its jute (J-EANMS) and glass(G-EANMS) composites were prepared by hand layup compression molding technique under 20 bar at 120°C for 5h. The structure of EANM was supported by FTIR and ¹HNMR spectroscopic techniques and also characterized by acid and hydroxyl values. Thermal properties of EANM and cured EANMS were evaluated by DSC and TGA at 10°C min^-1 heating rate in nitrogen atmosphere. EANM and EANMS are thermally stable up to 149o and 300°C and followed three and single step degradation kinetics. The energy of activation, frequency factor, degradation order and entropy change were evaluated and compared. J-EANMS and G-EANMS showed 38.2 and 184MPa tensile strength; 31.6 and 90.3 MPa flexural strength, 4.4 and 5.7 kVmm^-1 electric strength and 2.6x10¹² and 4.2x10¹² ohm cm volume resistivity, respectively. Good thermo-mechanical and electrical properties and excellent hydrolytic stability against different environments indicated its industrial utility as low load bearing housing, insulating material for electrical and electronic appliances and marine applications.
