Studies on thermal and microwave assisted synthesis of poly myristyl acrylate and its evaluation as viscosity modifier in lubricating oil

Abstract

Homopolymer of myristyl acrylate was synthesized by two different ways; microwave (MW) assisted method and thermal method using benzoyl peroxide (BZP) and azobis iso butyro nitrile (AIBN) as initiator. Additive performances of each of them as viscosity modifier (VM) for lubricating oil (lube oil) were also evaluated by standard ASTM methods. Thermal stability of the polymers was determined by thermo gravimetric analysis and shear stability of each of the polymers were also studied in different concentration of base oil. A comparison of their performances has also been evaluated and reported.
