| description | The present invention relates to a block copolymer comprising at least one polyalkadiene block which may or may not be hydrogenated and at least one random (aromatic vinyl compound-co-maleic anhydride) block. Besides, the invention relates to a stable polymer composition comprising a continuous phase formed by a first polymer and a phase dispersed therein of a second polymer, which second polymer is not compatible with the first polymer, and an amount of the block copolymer according to the invention, the ratio of the block copolymer to the second polymer ranging between 1:50 and 1:5. Finally, the invention relates to the use of the block copolymers according to the invention as compatibilizer and/or as modifier for the mechanical properties of polymer compositions.
L'invention concerne un copolymère séquencé comprenant au moins un bloc polyalcadiène qui peut être ou non hydrogéné, et au moins un bloc (composé vinylique aromatique-co-anhydride maléique) aléatoire. Elle concerne également une composition polymère stable comprenant une phase continue formée par un premier polymère et une phase, dispersée à l'intérieur de la phase continue, d'un second polymère, lequel second polymère n'étant pas compatible avec le premier, et une quantité de copolymère séquencé de l'invention, le rapport entre le copolymère séquencé et le second polymère se situant entre 1:50 et 1:5. L'invention concerne enfin l'utilisation des copolymères séquencés de l'invention comme agents de compatibilité et/ou modificateurs des propriétés mécaniques des compositions polymères. |
