Abstract

An ethylene copolymer, a catalyst system suitable to prepare the ethylene copolymer, and a process to prepare such ethylene copolymer are described. The use of the ethylene copolymer as impact modifier in polyethylene and as compatibilizer in a polymer blend are also described. The ethylene copolymer has a density from 0.855 g/cm3 to 0.910 g/cm3, a polydispersity Mw/Mn lower than 3.5, comprises at least one first ethylene polymer component and at least one second ethylene polymer component having different comonomer contents so as to show at least two predetermined CRYSTAF peak temperatures.
