Abstract

A composition comprising from 2 to 25 weight percent of at least one free radical ethylene polymer with a specific gravity between 0.91 and 0.94, and from 75 to 98 weight percent of at least one copolymer of ethylene and at least one .alpha.-olefin containing at least 4 carbon atoms, with a specific gravity between 0.905 and 0.940 and a melt index between 0.4 and 3 dg/minute, wherein the average proportion of .alpha.-olefin units in the copolymer is between 1 and 8 mole percent, wherein the copolymer comprises crystalline fractions and amorphous fractions, wherein the distribution of the .alpha.-olefin units in the copolymer is heterogeneous, and wherein the proportion of .alpha.-olefin units in the copolymer varies between at least 0.2 and at most 5 times the average proportion, depending on the fractions considered.
