A modified copolymer of ethylene and of at least one alpha -olefin having from 3 to 12 carbon atoms, comprising from 0.5 to 10 mole percent of units derived from the alpha -olefin, wherein the measured limiting viscosity of the copolymer is between 1.5 and 10 times the limiting viscosity of the copolymer calculated from the molecular weight distribution of the copolymer. Process for producing these copolymers employing at least one free-radical initiator. |
