Abstract[English]
A polymer composition comprising at least 95% by weight, based on the total weight of the composition, of at least one curable, oil-extended polybutadiene polymer obtained by blending a polybutadiene polymer with at least one oil, wherein the polybutadiene polymer has a 1,4-cis content of at least 92% and comprises at least 90% by weight, preferably at least 95% by weight, based on the weight of the polymer, of units derived from butadiene, wherein the oil comprises at least one ester of a glycerol and at least one carboxylic acid. Also provided are methods for preparing such compositions.[French]
La présente invention concerne une composition polymère comprenant au moins 95 % en poids, sur la base du poids total de la composition, d'au moins un polymère de polybutadiène durcissable étendu à l'huile obtenu par mélange d'un polymère de polybutadiène avec au moins une huile, le polymère de polybutadiène présentant une teneur en forme 1,4-cis d'au moins 92 % et comprenant au moins 90 % en poids, de préférence au moins 95 % en poids, sur la base du poids du polymère, de motifs dérivés du butadiène, l'huile comprenant au moins un ester d'un glycérol et au moins un acide carboxylique. L'invention concerne également des procédés de
préparation de telles compositions.
