Catalyst for polymerisation of styrene and dienes, preparation method thereof and use of same

Abstract

[FR] L'invention concerne un catalyseur pour la polymérisation de 1,4-diènes, de styrène et pour la copolymérisation des deux monomères. Il présente comme caractéristiques un degré élevé de stéréosélectivité, d'activité catalytique et de tolérance à la présence d'impuretés polaires. Ce catalyseur allie les caractéristiques propres des catalyseurs de polymérisation de diènes utilisant Ni (stéréosélectivité et activité catalytique élevés) à son caractère bien défini et à sa tolérance à sa présence de substances polaires. Sa préparation est par ailleurs simple, ce qui facilite son utilisation dans la pratique.

[EN] The invention relates to a catalyst for the polymerisation of 1,4-dienes, styrene and for the copolymerisation of two monomers. The characteristics of the inventive catalyst include a high degree of stereoselectivity, catalytic activity and tolerance to the presence of polar impurities. Said catalyst combines the characteristics specific to Ni-based diene polymerisation catalysts (high stereoselectivity and catalytic activity) with a well-defined character and tolerance to the presence of polar substances. The inventive preparation method is simple, thereby facilitating the practical use thereof.

[ES] Se trata de un catalizador para la polimerización de 1,4-dienos, de estireno, y para la copolimerización ambos monómeros. Presenta como características un alto grado de estereoselectividad, actividad catalítica y tolerancia a la presencia de impurezas polares.Este catalizador une las características propias de los catalizadores de polimerización de dienos basados en Ni (elevada estereoselectividad y actividad catalítica) a su carácter bien definido y su tolerancia a la presencia de sustancias polares. Su preparación es además sencilla, facilitando su uso en la práctica.
