What are biodegradable polymers ?

Explanation

Polymers which distintergrate by themselves over a period of time either by enzymatic hydrolysis or by bacterial degradation or oxidation in environment are called biodegradabic polymers. For examole , all biopolymers (polysaccharides, proteins , nucleic acid), and some synthetic polymers such as poly-`beta`-hydroxybautyrate -co-`beta`-hydroxyvalerate (PHBV), poly (glycollic acid) ply (lactic acid), i.e., dextron, nylon -2-nylon -6,etc.
