WebS. Sinha Ray, M. Bousmina, in Polymer Nanocomposites, 2006 3.2 Definition and categories of biodegradable polymers. Biodegradable polymers are defined as those that undergo microbially induced chain scission leading to the mineralization. Specific conditions in terms of pH, humidity, oxygenation and the presence of some metals are required to ensure the … WebSaturated and unsaturated compounds. In chemistry, a saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base. The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than ...
