Abstract

Starch is carbohydrate, which is naturally digested by organism or in other word can be disposable to the environment. Starch is also inexpensive natural biopolymer which totally biodegradable in a wide variety of environments. Natural starch exhibits a pronounced macromolecular structure, which is suitable for the production of bioplastics. However, prior to production of such materials, the structure of native starch should be suitably modified. This is necessary, because starch is a multi hydroxyl polymer. There were so vast intermolecular and intramolecular hydrogen bonds in starch that native starch is not a true thermoplastic.
