Traditional applications of synthetic polymers are mostly based on their relative inertness to biodegradation compared with natural macromolecules such as cellulose and proteins. Concerns about preventing or retarding attack on polymers by bacteria, fungi, insects, rodents, and other animals provided the early incentive for the study of the iodegradation of polymers. now the use of synthetic polymers has accelerated to the extent that he disposal of the polymer products currently in use, most of them bioresistant, has become increasingly dificult.
One of the important current incentives for the study of biodegradable polymers is their easier disposal. Moreover, biodegadable polymers are useful for applications such as sutures, surgical implants, controlled-release formulations of drugs and agricultural chemicals, agricultural mulch, etc, and interest in them continues to increase.
