Abstract Beschichtungen mit Trennaktivität zeichnen sich dadurch aus, dass das O/Si‐Verhältnis ca. 1:1 und das Kohlenstoff‐Siliziumverhältnis ca. 2:1 beträgt. Hieraus lässt sich folgern, dass für die Trennwirkung eine Struktur verantwortlich ist, die dem PDMS ähnlich ist und für die dreidimensionale Vernetzung ein erh…

Abstract Silica as reinforcing filler brings about a low hysteresis in elastomeric compounds. Aim of this work was to promote a better silica‐elastomer interaction by using, as minor ingredients of a compound, isoprene oligomers having a functional group as the chain end. The effect of the functionality was investigat…
