Abstract
Polyurethanes synthesized from diols of low, medium and high molecular weight ( Mw = 1000, 2000 and 3000 respectively) with low free isocyanates were used to fabricate coated fabrics. The physical, chemical and mechanical properties of these coated fabrics and polymer films were studied to establish their suitability for fabricating collapsible fuel tanks to store diesel for long periods under adverse conditions. Fabrics coated with low molecular weight polyurethanes are found to be more suitable for storing diesel fuel compared with those coated with medium and high molecular weight polyurethanes.
