✦ Synopsis

Polymers of individual and mixed normal C12, C14, CI6, and CIS a-olefins are synthesized, purified, and then characterized. The performance of poly-a-olefins is assessed for improving the cold flow properties of a local gas oil in terms of cloud-point and pour-point depression. Results show that poly-a-olefins have great potency in decreasing the pour point of the distillate fuel, whereas a slight effect is observed in decreasing the cloud point. Efficiency of the polymeric pour-point depressants is discussed on the basis of their structure and average molecular weight.
