Ethylene polymers having a linear structure and method for preparing", Abstract of the disclosure Particular ethylene polymers are described having a linear structure, that is a structure which is essentially devoid of lengthy branching offs and having a density less than 0.9450 g/cm.3. They are crystalline ethylene copolymers with at least another alpha olefin having a density comprised between 0.9150 and 0.9450 g/cm3 in which the con-, tents of comonomer varies from 1 molar % to 7 molar %. Such copolymers are further characterized by a melting point comprised between 115°C and 130°C and an X-ray crystallinity variable between 39% and 55% as a function of the quantity of comonomer, and a …
