Abstract: INTERPOLYMERS (ESPECIALLY COPOLYMERS) OF ETHYLENE AND PROPYLENE ARE OXIDIZED AND DEGRADED BY HEATING ABOVE 100* C. WITH AN OXYGEN-CONTAINING GAS, USUALLY AIR, IN THE PRESENCE OF AN ALIPHATIC AMINE. THE DEGRADED POLYMERS ARE CHARACTERIZED BY CAUSING SUBSTANTIALLY NO INCREASE IN THE LOW-TEMPERATURE FLUIDITY OF A FUEL OIL, AND ARE USEFUL AS VISCOSITY MODIFIERS FOR LUBRICANTS.

Abstract: Viscosity Index improvers for lubricating oils comprise a polymer of molecular weight above 100,000 e.g. a polymethacrylate, and a polymer of molecular weight below 25,000 e.g. a polyisobutylene. The low molecular weight polymer increases the shear-stability of high molecular weight polymer.
