Abstract

See full text

The present disclosure relates to an ethylene polymer composition having an eta (0.01) equal to or higher than 35,000 Pa·s, comprising:

    A) 25-75% by weight of an ethylene polymer selected from ethylene homopolymers, copolymers of ethylene with 10% or less of one or more olefin comonomers, and mixtures of the homopolymers and copolymers;B) 25-75% by weight of a copolymer of ethylene and propylene comprising 45-70% by weight of ethylene;wherein eta (0.01) is the complex shear viscosity at an angular frequency of 0.01 rad/s, measured with dynamic oscillatory shear in a plate-plate rotational rheometer at a temperature of 200° C., and the amounts of A) and B) refer to the total weight of A)+B).
