The present invention provides polymer blends having a first component of a polymeric material capable of being cross-linked and selected from the group consisting of an ethylene containing polymer, the first component present in an amount by weight of the blend from about (50 %) to about (95 %), the first component having a first melting point temperature determined by DSC; and a second component of a non-readily cross-linkable polymeric material and selected from the group consisting of propylene containing polymers and methyl pentene containing polymers, the second component being present in an amount by weight of the blend from about (50%) to about (5 %), the second component having a second melting point temperature determined by DSC; and a portion of the first component being crossed-linked and the second component is essentially free of cross-linking.
L'invention concerne des mélanges polymériques possédant un premier constituant de matière polymérique réticulable et choisi dans le groupe constitué d'un polymère contenant de l'éthylène, ce premier constituant représente en quantité en poids du mélange entre environ (50 %) et (95 %) et possède une première température de fusion déterminée par analyse calorimétrique différentielle (ACD); et un second constituant de matière polymérique difficilement réticulable et choisi dans le groupe constitué de polymères contenant du propylène et des polymères contenant du méthylpentène, ce second constituant représente en quantité en poids du mélange entre environ (50 %) et (5 %) et possède une seconde température de fusion déterminée par ACD, une partie du premier constituant étant réticulée et le second constituant étant sensiblement exempt de réticulation.
