The invention relates to a polymer composition containing a carbon-carbon backbone and an epoxide moiety pendant from said carbon-carbon backbone prepared by the process which comprises introducing into a polymer containing a carbon-carbon backbone a first monomer containing ethylenic unsaturation and an epoxide moiety thereby forming a polymer composition containing a carbon-carbon backbone and an epoxide moiety pendant from said carbon-carbon backbone and methods of making such a polymer composition. The polymer composition is useful to provide lubricating oils, for example lubricating oils of improved oxidative stability, dispersancy, and viscosity index which contain ethylene-propylene copolymer bearing allyl glycidyl ether or glycidyl methacrylate graft monomer - which has been functionalized with 2,5-dimethyl aniline or 2,6-dimethyl morpholine.
