Beschreibung
Zusammenfassung:	Described herein are thermoplastic vulcanizate compositions that include a thermoplastic matrix comprising a cyclic olefin copolymer and an oil and particles dispersed in the thermoplastic matrix and comprising an at least partially cross-linked rubber. The thermoplastic vulcanizate composition has a tanδ profile comprising a peak occurring between about -20 °C and about 90 °C and having a peak value between about 0.1 and about 2.0. Sont décrites ici des compositions de vulcanisat thermoplastique qui comprennent une matrice thermoplastique comportant un copolymère d'oléfine cyclique et une huile, des particules étant dispersées dans la matrice thermoplastique, et comportant un caoutchouc au moins partiellement réticulé. La composition de vulcanisat thermoplastique possède un profil de tanδ comprenant un pic se produisant entre environ -20 °C et environ 90 °C et ayant une valeur de pic comprise entre environ 0,1 et environ 2,0.
