Abstract
(EN)
There is disclosed a composition, suitable for use in dynamic applications at low temperature, the composition comprising a first polymeric material (A) having a repeat unit of formula -O-Ph-O-Ph-CO-Ph- I wherein Ph represents a phenylene moiety; and a second polymeric material (B) having a repeat unit of formula −(F2C−CF2)−II and further comprising a pigment; wherein said composition has a melt viscosity of at least 0.50 kNsm-2. There is also disclosed an assembly or apparatus, a use and a polymeric micropellet.
(FR)
L'invention concerne une composition, appropriée pour une utilisation dans des applications dynamiques à basse température, la composition comprenant un premier matériau polymère (A) ayant une unité de répétition de formule -O-Ph-O-Ph-CO-Ph-I, dans laquelle Ph représente une fraction phénylène; et un second matériau polymère (B) ayant une unité de répétition de formule -(F2C−CF2)-II et comprenant en outre un pigment; ladite composition ayant une viscosité à l'état fondu d'au moins 0,50 kNsm-2. L'invention concerne également un ensemble ou un appareil, une utilisation et une micropastille polymère.
