STYRENE/BUTADIENE DIBLOCK COPOLYMER-CONTAINING BLENDS THAT ARE NOT AN AGGLOMERATION AND A PROCESS FOR PREPARATION

STYRENE/BUTADIENE DIBLOCK COPOLYMER-CONTAINING BLENDS THAT ARE NOT AN AGGLOMERATION AND A PROCESS FOR PREPARATION

A process for producing a styrene-butadiene diblock copolymer- containing blend that is not an agglomeration, that involves mixing a styrene- butadiene multiblock thermoplastic elastomer solution with a styrene-butadiene diblock copolymer solution. Blends comprising a styrene-butadiene diblock copol...

Zusammenfassung:A process for producing a styrene-butadiene diblock copolymer- containing blend that is not an agglomeration, that involves mixing a styrene- butadiene multiblock thermoplastic elastomer solution with a styrene-butadiene diblock copolymer solution. Blends comprising a styrene-butadiene diblock copolymer and a styrene-butadiene multiblock thermoplastic elastomer, which blends are not an agglomeration. L'invention concerne un procédé de fabrication d'un mélange contenant un copolymère diséquencé styrène-butadiène qui n'est pas une agglomération, qui comprend le mélange d'une solution d'élastomère thermoplastique multiséquencé styrène-butadiène avec une solution de copolymère diséquencé styrène-butadiène. L'invention concerne également des mélanges comprenant un copolymère diséquencé styrène-butadiène et un élastomère thermoplastique multiséquencé styrène-butadiène, lesdits mélanges n'étant pas une agglomération.
