Abstract

Les compositions comprenant un copolymère linéaire tétra-séquencé et un copolymère linéaire bi-séquencé. Ces deux copolymères sont constitués de séquences polydiènes et de séquences polyvinylaromatiques, et le copolymère tétra-séquencé comporte en outre une portion constituée par des motifs monomères diènes et vinyl-aromatiques enchaînés de façon statistisque. Les compositions sont obtenues soit en mélangeant les composants polymères séquencés individuels, soit au moyen de nouveaux procédés de synthèse originaux qui permettent d'obtenir simultanément les deux copolymères séquencés. Les compositions conviennent pour tous les usages pour lesquels sont nécessaires de bonnes propriétés de résistance au choc, de transparence et d'aptitude à la mise en oeuvre.
