Biodegradable materials are prepared by reaction of untreated and/or treated starch with vegetable fats, oils and/or their processed products to medium to high degrees of substitution to derivatise and to render the starch hydrophobic. USE - The biodegradable starch based materials are useful for the production of packaging, composite materials for the automotive industry and as an adhesive for paper-aluminium composites. ADVANTAGE - The derivatised starch products are biodegradable and have low solubility in water and may be used at upto 60% in polymers and polymer mixtures. The processing of the starch is cost effective.
