Hydorgels have been traditionally used in variousindustries as superabsorbent polymers. In the pastfew years its applications intensified by emerginghot topics such as tissue engineering and drugdelivery. Polyethylene oxide (PEO) and its lowermolecular weight brothers, polyethylene glycol(PEG), are gaining interest due to theirbiocompatibility and FDA approval. This steady growof popularity of Hydrogels and PEO in academia andindustry has not been addressed in a proper way. Manyscientists are not familiar with different methods ofsynthesis and characterization of hydrogels. Thisbook, therefore, provides the methods of synthesisand characterization including, postpolymerization(curing), swelling, mechanical and theoreticalmeasurements as well as dynamic mechanical analysis.The content should help shed some light on thisexciting and fast growing topic, and should beespecially useful for professionals in Chemicalengineering, Biomedical engineering, MaterialsScience, Pharmacy and Medicine.
