VISCOSITY INDEX IMPROVER FOR POLY (ALKYL METHACRY LATE) CONCENTRATED SOLUTIONS
Journal Title: Journal of Science And Arts - Year 2013, Vol 25, Issue 4
Abstract
To establish the ability of copolymer poly (alkyl methacrylate) solutions in rapeseed oil as solvent to perform at low and high temperatures in a vehicle’s engine, that is their capacity to improve the oil’s viscosity index, the viscosity/temperature characteristics of their 5, 8, 12 and 18% solutions were determined. It was obtained polymer increase very much the viscosity index, as much as it concentration is higher. The introduction of copolymer poly (alkyl methacrylate) in rapeseed oil viscosity index increases by 73 units at the 5%, 85 units for solution of 8%, 99 units for a 12% solution and 109 units for 18% solution.
