ABSTRACT
Biodegradable polymers can be deŽned as those that undergo a signiŽcant change in chemical structure under speciŽc environmental conditions. These changes result in a loss of physical and mechanical properties, as measured by standard methods. Biodegradation is deŽned by standard methods like International Standard Organization (ISO), American Society for Testing of Materials (ASTM), European Committee for Standardization (CES), and others. For example, the ISO standards take into account the conversion of organic carbon in CO2 and at the CES standards, this evaluation is carried out through the mass loss and fragmentation of the material.
