Abstract[English]
A counter tapered diblock copolymer composition comprises a monovinyl aromatic monomer A polymerized with a conjugated diene monomer B to form the structure A- [A/B], where the [A/B] block is a copolymer of the A and B monomers that is counter tapered, which means the ratio of B to A is lower proximal to the A block relative to the ratio of B to A distal to the A block. The [A/B] block preferably has a vinyl content that is higher proximal to the A block relative to the vinyl content distal to the A block. The diblock copolymer is preferably partially coupled or formed with a multifunctional initiator to provide a mixture of the diblock copolymer composition and a linear (A- [A/B])-X-([B/A]-A) structure and/or a coupled radial and/or multiarm structure (A- [A/B])n-X, where X is the residue of a coupling agent or an initiator. Asphalt and adhesive compositions are made with the diblock copolymer composition and with the mixture.[French]
Une composition de copolymère dibloc contre-conique comprend un monomère aromatique monovinylique A polymérisé avec un monomère diène conjugué B pour former la structure a-[A/B], le bloc [A/B] étant un copolymère des monomères A et B qui est contre-conique, ce qui signifie que le rapport de B à A est inférieur à proximité du bloc A par rapport au rapport de B à A à distance du bloc A. Le bloc [A/B] présente de préférence une plus haute teneur en vinyle à proximité du bloc A par rapport à la teneur en vinyle à distance du bloc A. Le copolymère dibloc est de préférence partiellement couplé à un initiateur multifonctionnel, ou formé avec ce dernier, pour fournir un mélange de la composition de copolymère dibloc et une structure linéaire (A-[A/B])-X-([B/A]-A) et/ou une structure radiale et/ou multibras couplée (A-[A/B])n-X, X représentant le résidu d'un agent de couplage ou d'un initiateur. Des compositions d'asphalte et d'adhésif sont fabriquées avec la composition de copolymère dibloc et avec le mélange.
