Biodegradable and Bio-Chemical Polymers
A polymer that can be decomposed by microorganism is named as biodegradable polymer. The biodegradable polymers are the polymers which are degraded by the micro-organism within a suitable period so that biodegradable polymers & their degraded products do not cause any serious affects on the environment. The decomposition reactions involve hydrolysis to non- toxic small molecules which may be metabolized by or excreted from the body. Biological polymers are large molecules composed of the many similar smaller molecules coupled along in an exceedingly chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers Natural polymers are used to build tissue and other elements in living organisms.
