Title (DE) VERFAHREN ZUR HERSTELLUNG KAUTSCHUKHALTIGER THERMOPLASTISCHER FORMMASSEN
(EN) METHOD FOR PRODUCING THERMOPLASTIC MOLDING MATERIALS CONTAINING RUBBER
(FR) PROCEDE DE PREPARATION DE MATIERES A MOULER THERMOPLASTIQUES CONTENANT DU CAOUTCHOUC
Abstract:
(DE) Verfahren zur Herstellung kautschukhaltiger thermoplastischer Formmassen, bei dem mindestens ein kautschukelastisches Polymerisat A und mindestens ein thermoplastisches Polymeres B durch Polymerisation hergestellt und miteinander vermischt werden, wobei das kautschukelastische Polymerisat A nach der Polymerisation in einer wässrigen Phase dispergiert vorliegt, dadurch gekennzeichnet, dass man nach Abschluss der Polymerisation von Komponente A der wässrigen Phase mindestens ein pH-Puffersystem zufügt.
(EN) The invention relates to a method for producing thermoplastic molding materials containing rubber, according to which at least one rubber-elastic polymerizate A and at least one thermoplastic polymer B are produced by polymerization and are mixed together. After polymerization, the rubber-elastic polymerizate A exists while dispersed in an aqueous phase. The invention is characterized in that at least one pH buffer system is added to the aqueous phase after the polymerization of constituent A is completed.
(FR) La présente invention concerne un procédé de préparation de matières à mouler thermoplastiques contenant du caoutchouc, dans lequel au moins un polymère élastique caoutchouteux A et au moins un polymère thermoplastique B sont produits par polymérisation et mélangés. Selon l'invention, le polymère élastique caoutchouteux A est présent, après polymérisation, à l'état de dispersion dans une phase aqueuse. Le procédé se caractérise en ce que, après polymérisation du composé A, au moins un système tampon de pH est ajouté à la phase aqueuse.
