摘要：
Twelve terpolymeric additives were prepared via free radical chain addition polymerization. The rheological properties of lube oil (SAE-30) were studied with and without additives. The prepared terpolymers have a good effect on the viscosity-temperature relationship. The flow curves and viscosity-shear rate curves of the prepared additives doped with lube oil were studied and it was found that they behave as Bingham fluids. The sensitivity of the prepared terpolymers to mechanical stresses was studied and it was found that the sensitivity increases with increasing the molecular weight of the prepared additives.
