Synthesis Charachterization (Thermogravimetric Analysis) Of Glass Reinforcement Materials (Non-Conducting Materials)

Abstract

REINFORSEMENT MATIRIALS: - Poly (urethane-imide) s (PUIs) was prepared by the by the intermolecular Diels-Alder (DA) Reaction of Hexamethylene bis (2-Furanylmethythioethyl carbamate) (HMFTC) with various bismaleimides. The DA reaction was carried out in 1, 4 dioxane as a solved as well as in bulk, followed by aromatization of tetrahydro phthalimide intermediates in the presence of acetic anhydride. All the polymers were characterized by elemental analysis, IR spectral studies and thermogravimetry. The PUIs exhibit moderate thermal stability. HMFTC and bismaleimides were polymerized (at 145 + 10 0C) by DA intermolecular reaction into moderately thermally stable PUIs glass-fibre composite (i.e. laminates) and were characterized by their chemical resistance and mechanical properties.
