The synthesis of polymer from starch, glycerol, sorbitol, and maleic anhydride using HCl as catalyst is carried out. The polymer obtained has an average molar mass of 1863 g/mol. This and other physico-chemical properties of this polymer are presented. The ester group in the polymer is confirmed by IR and NMR spectral studies. The COD and BOD study of polymer is also presented. The BOD shows first the increase and then decrease during the course of 10 days of analysis.
