Abstract[English]
of at least 80% by weight based on the weight of the filler and is obtained from a biomass ash comprising rice husk ash and wherein the conjugated diene polymer is a homopolymer of a conjugated diene or a copolymer of at least one conjugated diene selected from the group consisting of butadiene, isoprene, 1,3-pentadiene, 2,3-dimethyl- butadiene, 1-phenyl-1,3-butadiene, 1,3-hexadiene, and wherein the polymer is functionalized and comprises at least one functional group. Also provided is a method of making a vulcanizable rubber compound comprising combining the conjugated diene polymer with the silica, and a method of making an article comprising subjecting a curable composition comprising the compound and a curing agent capable of curing the conjugated diene polymer to at least one curing reaction. Further provided are articles obtained from the compounds.[French]
d'au moins 80 % en poids sur la base du poids de la charge et étant obtenue à partir d'une cendre de biomasse comprenant des cendres de balle de riz et le polymère de diène conjugué étant un homopolymère d'un diène conjugué ou d'un copolymère d'au moins un diène conjugué choisi dans le groupe constitué par le butadiène, l'isoprène, le 1,3-pentadiène, le 2,3-diméthyl-butadiène, le 1-phényl-1,3-butadiène, le 1,3-hexadiène, et le polymère étant fonctionnalisé et comprenant au moins un groupe fonctionnel. L'invention concerne également un procédé de fabrication d'un composé de caoutchouc vulcanisable comprenant la combinaison du polymère de diène conjugué avec la silice, et un procédé de fabrication d'un article comprenant la soumission d'une composition durcissable comprenant le composé et un agent de durcissement capable de durcir le polymère de diène conjugué à au moins une réaction de durcissement. L'invention concerne en outre des articles obtenus à partir des composés.
