Abstract
Acetylation of high amylose (50%) maize starch to high degree of substitution (DS) was synthesised by reacting starch with acetic anhydride using sodium hydroxide as the catalyst. Starch Acetate was dissolved in Dimethyl Sulphoxide (DMSO), the DS of which ranged from 0.8 to 1.8. Ultrafine fibers were made by the method of electrospinning. FTIR, NMR and SEM were used to characterize the structure and surface morphology of the product.
