What are biodegradable polymers ? Give example.

Explanation

Almost all synthetic polymers are quite resistant to the environmental degradation processes and are thus responsible for the accumulation of polymeric solid waste materials. Thee polymeric waste materials remain undegraded for quite a fong time and thus cause environmental problemsc To solve this environmentai problem new biodegradable synthetic polymers have been designed and developed. These polymers contain functional groups similar to the Functional groups present in biopolymers and. as such as quickly biodegraded by .the micro-organisms present in the enviromnent. An important e.g. of biodegradable aliphatic [polymer]5 is poly -`beta` -hydroxybutyrate - Co -`beta`- hydrovalerate (PHBV), Polyglycolic acid (PGA) and Polylactic acid (PLA).
