Abstract

L'élastomère fonctionnalisé (EF) est formé d'un substrat élastomère, ayant une masse moléculaire moyenne en poids (a) entre 10000 et 600000 daltons et un indice de polydispersité inférieur à 5, sur lequel sont greffées, en quantité allant de 0,1 % à 10 % en poids du substrat, des séquences (b) où R1 est un radical hydrocarboné (x+z+1)-valent en C1 à C12, X représente H ou un radical hydrocarboné monovalent R en C1 à C12, z est égal à zéro ou 1 et x est un nombre entier allant de 1 à 3, avec x+z 3, la masse moléculaire moyenne en poids (Mw) dudit EF étant telle que le rapport (c) soit inférieur à 20 %. On produit des compositions bitume/EF utilisables pour la réalisation de revêtements en incorporant ledit EF à une composante bitumineuse.The functionalized elastomer (EF) is formed of an elastomeric substrate, having a weight-average molecular mass (a) between 10,000 and 600,000 daltons and a polydispersity index of less than 5, onto which are grafted, in an amount ranging from 0, 1% to 10% by weight of the substrate, of the sequences (b) where R1 is a hydrocarbon radical (x + z + 1) -valent in C1 to C12, X represents H or a monovalent hydrocarbon radical R in C1 to C12, z is zero or 1 and x is an integer ranging from 1 to 3, with x + z 3, the weight average molecular weight (Mw) of said EF being such that the ratio (c) is less than 20%. Bitumen / EF compositions that can be used for the production of coatings are produced by incorporating said EF into a bituminous component.
