ABSTRACT:
A method and apparatus of taking a solid, high molecular weight EPM or EPDM polymer into solution in oil as a shear stable viscosity index improver comprising passing the polymer through an extruder at elevated temperature for degradation of the polymer and circulating hot oil across the die face of the extruder while reducing the degraded polymer to particle size upon issuance from the extruder and into the hot oil.
