Abstract
L'invention concerne une composition de copolymère utile en tant que modificateur de cristaux de paraffine et agent améliorant l'écoulement. Les compositions sont des copolymères d'un fumarate dialcoylique C¿6? à C¿250? à chaîne droite ou ramifiée et d'au moins un composé choisi dans le groupe comprenant du monoxyde de carbone, de l'.alpha.-oléfine C¿3? à C¿30?, de l'éthylène, du styrène et de l'acétate de vinyle.
