Abstract

Copolymère d'éthylène et d'au moins un comonomère contenant au moins 4 atomes de carbone, qui est caractérisé par une polydispersité supérieure à 2, une large transition du point de fusion telle que mesurée par l'analyse calorimétrique différentielle à compensation de puissance, et une répartition étroite de la composition. Des copolymères éthylène/C¿4+? peuvent également présenter au moins un point de fusion maximal supérieur au point de fusion maximal d'un copolymère statistique ayant la même composition d'unités monomères. Ces copolymères sont obtenus par mise en contact d'éthylène et d'un comonomère dans des conditions de polymérisation en présence d'un système de fluxion catalyseur approprié.
