Solvent Free Microwave Assisted Synthesis of Poly Myristyl Acrylate—Characterization and Evaluation as Additives for Lubricating Oil

Abstract

Homopolymer of myristyl acrylate was prepared by microwave assisted free radical polymerization method using BZP as initiator with variation of time at a fixed power without any solvent. Characterization of the polymers was done by IR, NMR, and viscometric analysis. Additive performances of each of them (pour point depressant [PPD] and viscosity modifier [VM]) for lubricating oil (lube oil) were also evaluated by standard ASTM methods. A comparison of their performances has also been reported. The molecular weights of the polymers were determined from viscosity measurements in toluene at 313 K and thermal stability was measured by thermogravimetric analysis.
