An aryl group containing phosphite, such as triphenyl phosphite, can be added to a reaction mixture comprising an organophosphorus compound, phosphorus pentoxide and an alkylene oxide, optionally in the presence of a reagent for the incorporation of hydroxy functionality in the final product. The aryl group containing phosphite is employed to improve the color characteristics of the resulting oligomeric organophosphorus composition.
L'invention concerne un groupe aryle renfermant du phosphite, tel que du phosphite de triphényle, qui peut être ajouté à un mélange réactif comprenant un composé organophosphoré, du pentoxyde phosphoré et un oxyde d'alkylène, éventuellement en présence d'un réactif afin d'incorporer une fonctionnalité hydroxy dans le produit final. Le groupe aryle contenant du phosphite est utilisé pour améliorer les caractéristiques chromatiques de la composition organophosphorée oligomérique obtenue.
