Abstract
The present paper comprises synthesis and characterization of 2,3-epoxypropyl 3-(2-furyl)acrylate (EPFA) from 3-(2-furyl)acrylic acid (FAA) and epichlorohydrin, and its subsequent copolymerization with acrylonitrile (EN) by varying the ratio of EPFA:AN and time using benzoyl peroxide as initiator at 80°C in toluene. The resultant pre-polymers were characterized by epoxy equivalent weight (EEW), viscosity measurement, gel permeation chromatography (GPC), and infrared (IR) spectral studies. The prepolymers were cured by employing two different curing agents viz. chlorosulfonic acid (ClSO 3 H) and maleic anhydride/triethanolamine (MAN:TEA). The curing study was performed isothermally at 120 and 160°C, respectively, for the agents employed. Differential scanning calorimetry (DSC) was also employed to study the curing behavior on dynamic runs. The cured samples were analyzed by thermogravimetry for their thermal stability. The glass fiber reinforced composites (GFRC) were fabricated from selected resin samples and were characterized for their mechanical properties, electrical properties and chemical resistance.
