Abstract
A blend and a process for producing that blend in which a high ethylene content ethylene-propylene polymer and a lower ethylene content ethylene-propylene polymer are subjected to simultaneous blending and shearing to reduce their molecular weights and molecular weight distribution and to yield a product that can be recovered as a solid using conventional plastic processing equipment. The sheared blend of polymers can function as a shear stable viscosity index improver with improved lower temperature properties.
