Beschreibung
Zusammenfassung:	A light-stabilized thermoplastic elastomer comprising a blend of thermoplastic resin and unsaturated rubber, which rubber has been dynamically vulcanized by hydrosilylation in the presence of a hindered amine light stabilizer compound which is free of sterically unhindered amine functionality. L'invention concerne un élastomère thermoplastique photostabilisé comprenant un mélange de résine thermoplastique et de caoutchouc insaturé. Ce caoutchouc a été préalablement soumis à une vulcanisation dynamique par hydrosilylation en présence d'un composé photostabilisateur amine encombrée qui ne comporte pas de fonctionnalité amine dépourvue d'encombrement stérique.
