Abstract: front page image
(DE)Die vorliegende Erfindung betrifft Diblockcopolymere der Formel A-B, die aufgebaut sind aus einem Polymerblock A, der im Wesentlichen aus α-Olefin-Einheiten mit 6 bis 22 Kohlenstoffatomen aufgebaut ist, und einem Polymerblock B, der im Wesentlichen aus Isobuten-Einheiten aufgebaut ist, ein Verfahren zu ihrer Herstellung, ihre Verwendung in Schmierstoffzusammensetzungen sowie Schmierstoffzusammensetzungen, die solche Diblockcopolymere enthalten.
(EN)The invention relates to diblock copolymers of formula A-B which are constituted of a polymer block A which is substantially constituted of α-olefin entities with 6 to 22 carbon atoms, and a polymer block B which is substantially constituted of isobutene entities. The invention also relates to a method for producing said diblock copolymers, to their use in lubricant compositions and to lubricant compositions containing said diblock copolymers.
(FR)L'invention concerne des copolymères biséquencés de formule A-B, constitués d'une séquence polymère A, comprenant principalement des motifs α-oléfine contenant de 6 à 22 atomes de carbone, et d'une séquence polymère B, comprenant principalement des motifs isobutène. L'invention concerne également un procédé de préparation desdits copolymères biséquencés, l'utilisation de ces derniers dans des compositions de lubrifiants ainsi que des compositions de lubrifiants contenant de tels copolymères biséquencés.
