摘要： The compositions contain a) less than 90% and at least 2% by weight of at least one ethylene polymer (A), and optionally, at least one .alpha.-olefin having from 3 to 12 carbon atoms, said polymer containing at least 70% in moles of patterns derived from ethylene, and b) more than 10% and up to 98% by weight of at least one polymer (B) containing at least 85% in moles of patterns derived from at least one .alpha.-olefin having from 3 to 12 carbon atoms and at the most 15% in moles of patterns derived from ethylene, and are characterized in that the polymer (A) is a modified polymer of which the measured limit viscosity is comprised between 1.3 and 100 times its limit viscosity calculated from the distribution of molecular masses. The compositions are obtained by a process consisting in providing a polymer of ethylene and, optionally, of at least one .alpha.-olefin having from 3 to 12 carbon atoms in the presence, on the one hand, of at least one initiator of free radicals in a quantity comprised between 0.001 and 0.3 parts by weight of the initiator for one hundred parts by weight of said polymer at a temperature higher than the melting temperature of said polymer during a time at least equal to one tenth of the half life time of the initiator at the temperature considered, and, on the other hand, of at least one polymer (B). Application to the production of industrial articles by extrusion-blowing of sheaths or hollow bodies, extrusion of films by means of flat dies, roto-moulding, injection or coating.
