Poly (vinyl alcohol) Hydrogels For Delivery of Diltiazem Hydrochloride

Polymer Hydrogels belong to most versatile materials of this world. They are widely used in food processing, cosmetics, pharmaceuticals, agriculture and advanced biotechnology. The supreme ability of such crosslinked polymers to absorb large amounts of water makes them ideal for storage and transportation of active biomolecules. Chapter 1 discusses, in detail, about the basics of Hydrogels, their classification, fabrication, probable applications and the scope and objective with special importance on PVA. Chapter 2 is the experimental. It contains the list of materials with their specifications, details of sample preparation and the experimental techniques used for the investigation. 3 to 5 entails results and discussion of differently treated high and low molecular weight PVA. Chapter 6 is the conclusion. It summarizes all observations of the work.
