Title
(EN) PROCESS FOR MAKING AND USING BISARYL DIPHOSPHATES
(FR) PROCEDE DE FABRICATION ET D'UTILISATION DE BISARYL-DIPHOSPHATES
Abstract
(EN)
Flame retardancy is provided to polymer resins by adding to the resin a bisaryl diphosphate that has not been purified to remove catalyst or catalyst residue from the product. The bisaryl diphosphate may be prepared by a two-step process that starts with the semi-continuous addition of dry bisphenol A to a heated mixture of phosphorous oxychloride and MgCl, and concludes with the addition of dry phenol to the step one intermediate.
(FR)
Des propriétés retardatrices de flamme sont conférées à des résines polymères par ajout à la résine d'un bisaryl-diphospate n'ayant pas été purifié en vue d'éliminer du produit le catalyseur ou le résidu de catalyseur. Le bisaryl-diphosphate peut être préparé au moyen d'un procédé en deux étapes, dont la première consiste à ajouter de façon semi-continue du bisphénol A sec à un mélange chauffé d'oxychlorure de phosphore et de MgCl, et la deuxième consiste à ajouter du phénol sec au produit intermédiaire obtenu au cours de la première étape.
