ABSTRACT
Epoxy resins are a class of reactive pre polymers and polymers which contain epoxide groups. Inspite of their high costs the epoxy resins find many important applications. The resins are used in both molding and laminating technique for making glass fiber-reinforced articles which are having better mechanical strength chemical resistance and electrical insulating properties. They also use in casting, potting encapsulating and embedment in the electrical and tooling industries. The general important uses are industrial flooring adhesive foams, highway surfacing patching material and stabilizers for vinyl resins. Epoxy resins may be reacted either with them- selves through catalytic homo polymerization or with a wide range of co-reactant like amino acid ,phenol, alcohols and thiols. These co-reactants are referred to as curatives. When linear epoxy resins react with suitable curative to form three dimensional cross linked thermo state structure. Epoxidation of unsaturated alcohol is carried out with the help of superoxide. The electrochemical generation of super-oxide anion and subsequent electro oxidation in situ is found to be advantageous and easy over the conventional technique. The work extended further in persuasive oxygen reduction studies on non-metallic surface such as different types of carbon and graphite with a view to understand the reaction mechanism and possible application to fuel cell technology.
