Abstract:
(EN) A purpose of the present invention is to provide a catalyst composition of high polymerization activity. Another purpose is to provide a polymer production method. Another purpose is to provide a polymer produced according to said polymer production method. Another purpose is to provide a rubber composition containing said polymer. Another purpose is to provide a tire using said rubber composition. Provided is a catalyst composition containing a compound represented by structural formula I (wherein said compound comprises an OH group in at least one bipyridyl ring; M is a transition metal, a lanthanoid, scandium, or yttrium; R1 and R2 are hydrocarbon groups comprising one or more carbon atoms, or halogen atoms; and R1 and R2 may be identical or different). Provided is a polymer production method including a step for polymerizing, in the presence of said catalyst composition, at least one selected from the group consisting of conjugated diene compounds and compounds comprising ethylenically unsaturated double bonds. Provided is a polymer produced according to said polymer production method. Provided is a rubber composition containing said polymer. Provided is a tire using said rubber composition.
(FR) L'objectif de la présente invention est de fournir une composition de catalyseur présentant une activité de polymérisation élevée. Un autre objectif est de fournir un procédé de production de polymère. Un autre objectif est de fournir un polymère produit selon ledit procédé de production de polymère. Un autre objectif est de fournir une composition de caoutchouc contenant ledit polymère. Un autre objectif est de fournir un pneu à l'aide de ladite composition de caoutchouc. L'invention concerne une composition de catalyseur contenant un composé représenté par la formule structurale I (dans laquelle ledit composé comprend un groupe OH dans au moins un cycle bipyridyle ; M est un métal de transition, un lanthanide, du scandium ou de l'yttrium ; R1 et R2 représentent des groupes hydrocarbonés comprenant un ou plusieurs atomes de carbone, ou des atomes d'halogène ; et R1 et R2 peuvent être identiques ou différents). L'invention concerne un procédé de production de polymère comprenant une étape de polymérisation, en présence de ladite composition de catalyseur, d'au moins un composé choisi dans le groupe constitué de composés diènes conjugués et de composés comprenant des liaisons doubles éthyléniquement insaturées. L'invention concerne également un polymère produit selon ledit procédé de production de polymère. L'invention concerne une composition de caoutchouc contenant ledit polymère. L'invention concerne un pneu utilisant ladite composition de caoutchouc.
