Abstract

La présente invention concerne la production de polymères de dichlorophosphazène pratiquement linéaires et solubles dans le benzène. Ces polymères sont de formule (NPCl2 )x dans laquelle x est compris entre 20 et 50 000; ils sont préparés à partir d'un oligomère cyclique de formule (NPCl2 )n , dans laquelle n va de 3 à 9, en particulier à partir du trimère (NPCl2 )3 ou du tétramère (NPCl 2 )4 , en présence d'une quantité convenable d'un halogénure métallique inorganique, notamment de nickel, cobalt, chrome, magnésium, cuivre, fer ou manganèse. L'invention permet de régler le poids moleculaire du produit obtenu et d'éviter la formation de grandes quantités de gel.
