Enhancement the ability to pump crude oil using rubber solutions

In this research, synthetic rubber (polystyrene-butadiene) and natural rubber (polyisoprene) were dissolved in a common solvent (Toluene) to prepare polymeric solutions by using magnetic mixer at temperatures of 35-45°C. It was observed that the degree of solubility for natural rubber was greater than that one for synthetic rubber. There is an increase in the viscosity and torque for both rubbers along with increasing the synthetic and natural rubbers concentration. Laminar behavior is observed for both polymers since Reynolds number is less than 2300. Natural rubber is more suitable to use in pipes with crude oil (paper)
