Beschreibung
Zusammenfassung:	The invention relates to hydroxybenzophenone-based compounds of formula (I) that are used to improve UV, thermal, and thermo-oxidative stability of high performance aromatic polymers in a blend or as end-cappers of the same polymers. L'invention concerne des composés à base d'hydroxybenzophénone de formule (I), qui permettent d'améliorer la stabilité aux UV, la stabilité thermique et la stabilité thermo-oxydante de polymères aromatiques haute performance dans un mélange ou comme fonctions pour le traitement de "end capping" de ces mêmes polymères.
