The Synthesis and Characterization of Homo Polymer of Acrylate of Mixed Alcohol and Their Performance as Additives for Lubricating Oils

摘要

Homopolymer of acrylate of a mixture of myristyl (C14), dodecyl (C12), and decyl (C10) alcohols in 2:1:1 molar ratio was synthesized by two different ways, microwave-assisted method and thermal method using benzoyl peroxide as initiator. The polymers were characterized by spectroscopic (NMR, IR) and viscomctric analysis. Performances of each of them as a pour point depressant and viscosity modifier for lubricating oil (lube oil) were also evaluated by standard ASTM methods. Oil thickening property of the polymers has also been investigated and reported here. Thermal stability of the polymers was determined by thcrmogravimetric analysis.
