Abstract
EP polymer of low molecular weight containing 0.02% to 0.6% by weight vinyl norbornene or norbornadiene whereby the cold flow of the EP polymer is improved with resultant improvement in recoverability and handling without noticeable modification in molecular weight distribution or shear stability and without interfering with the use thereof as an oil additive, and without so much as to decrease oil solubility rate.
