| Summary: | The notable increase in global consumption of plastics and thei r long residence time in the atmosphere show the great need for biodegradable products. In this project, we developed biodegrad able polymers based on citric acid and glycerol. Their synthesi s was carried out at different conditi ons of constant temperature and concentration and they were synthesized using an economically viable method. Characterization was un dertaken using: Acid number, FTI R spectroscopy, refractive index, viscosity, impact analysis, tensile test, hardness, calorimetry, the % humidity (oven method with recirculatingair), and density determination, along with qualit ative evidence to corroborate their biodegradability. These elaborate d polymers were mixed with medical grade PVC formulation, obtaining a hybrid polymer, showing their m echanical properties were changed. |
