Polymer blend: a new approach towards flow improvement of crude oil

Crude oil extraction, transportation and even its storage require a lot of struggle due to its high density, high viscosity and high pour point. To overcome these problems, polymers have attracted much attention as efficient chemical additive. Moreover polymer blending is an economic and easy process to develop better polymeric materials with higher thermal and mechanical stability. In this context, we evaluated a polymer blend of two copolymers viz. vinyl acetate-octyl acrylate and dodecyl acrylate-methyl methacrylate, as flow improver by measuring viscometric parameters, pour point and shear stability index in crude oil.
