Branched block ethylene polymers prepared from a narrow ethylene polymer, an ethylenically unsaturated functionalized organic compound, and reactive thermoplastic polymer, and methods of preparing such branched block ethylene polymers, are useful to prepare an impact modified ethylene polymer. La présente invention concerne des polymères blocs d'éthylène ramifiés préparés à partir d'un polymère d'éthylène étroit, un composé organique fonctionnalisé éthyléniquement insaturé et un polymère thermoplastique réactif; elle concerne aussi des procédés de préparation de tels polymères blocs d'éthylène ramifiés, utiles pour préparer un polymère d'éthylène modifié par impact.
