Synthesis and Evaluation of N-heterocyclic Compound as Antioxidant and its Influence on physico-mechanical and electrical Properties of Acrylonitrile-Butadiene Rubber

摘要

Rubber that constructed from unsaturat-ed copolymers are used in the most in-dustrial applications.However,they suffer from oxidation by heat,oxygen and light which lead to decrease their impor-tance.Acrylonitrile-butadiene rubber(NBR)is the most important one of the family of unsaturated copolymers which incorporated in many industrial applications such as manufacturing of seals,oil field packers,hydraulic hoses and auto-motive rubber products industry [1-4].Because of unsaturated double bonds in the butadiene units that are sensitive to heat and oxygen lead to decrease the heat resistance of NBR [5-7].
