Abstract
Degraded molecular weight copolymers of ethylene alpha-olefin are provided. The ethylene alpha-olefin copolymers, before degradation, are characterized by having a narrow molecular weight distribution and are comprised of intramolecularly heterogeneous and intermolecularly homogeneous copolymer chains. The degraded copolymers are useful as viscosity index improvers for oils.
