Styrene butadiene rubber as a viscosity improver: Experimental investigations and quantum chemical studies:

摘要: The limited viscosity range of vegetable oils restricts their effectiveness as a lubricant in numerous applications. In this work, the improvement with styrene butadiene rubber an additive sesame oil is studied and results are compared those commonly used improver, ethyl vinyl acetate, using rheometer. Sesame oil/styrene blends show higher increment than oil/ethyl acetate blends. variations further validated Arrhenius model. A computational quantum chemical software, Gaussian 09, to evaluate binding energies between molecules. Ground state electronic structures molecules modeled density functional theory. Thermal properties such flash, fire, pour points have also been evaluated for Chemical oxygen demand biological parameters chosen biodegradability ...
