ABSTRACT:
High- and medium density polyethylene compositions become extrudable and cross-linkable during the extrusion step by incorporating therein a free radical generator and an additive for plasticizing the polyethylene composition, at a relatively low extrusion temperature insufficient to decompose the free radicals generator, consisting of a C.sub.14 to C.sub.24 n-alkyl acrylate polymer having an average molecular weight by number of from 500 to 50,000, used in a proportion from 0.5 to 10% by weight.
