An ethylene and α-olefin copolymer having a specific molecular weight distribution, density, and side chain branching is provided. A molar mass distribution M w / M n of 1-8, a density of 0.85-0.94 g / cm 3 , a molar mass M n of 10,000-4000 000 g / mol, and a CDBI of less than 50%. a maximum of the side chain branching of the individual peaks of the short chain branching distribution exceeds each case 5CH 3/1000 carbon atoms, copolymers of ethylene and α- olefin, method for preparing them, their Catalyst systems suitable for production, as well as fibers, molded articles, films or polymer mixtures in which these copolymers are present.
