Experimental Evaluation of Poly Methacrylates as Additive on the Pour Point of the Oil

Addition small amounts of specific compound, which is called additives can to lubricating oils enhance wax crystallization in the oil and improve pour point of the lubricants. In this research effect of such compounds on the pour point were investigated. Results show addition of specific additive (in this research Dodecilpolymethacrylate and Tetra do decilpolymethaciylate) is improved pour point of the oil but the relation between pour point decrease and additive concentration is not linear. Also simultaneously effect of dilutant and additive was studied. Use of a dilutant and an additive simultaneously is more efficient than additive.
