Abstract

On décrit une composition à stabilisant préalablement formé, à base d'un stabilisant précurseur que l'on peut obtenir en faisant réagir un composé contenant un atome de silicium avec un polyol de polyéther. Ledit composé répond à la formule R¿n?SiX¿4-n? ou R¿n?Si((-OSi(R?1¿)¿2?)¿p?X)¿4-n?, dans laquelle les groupes R représentent indépendamment des groupes hydrocarbyle saturés ou insaturés, un groupe R au moins étant un groupe hydrocarbyle alcénique; R?1¿ représente un groupe hydrocarbyle, X représente un groupe alcoxy C¿1?-C¿10?, n est un nombre entier compris entre 1 et 3 et p est un nombre entier supérieur à zéro. Le polyol de polyéther présente un poids moléculaire moyen supérieur à 400 ainsi qu'un nombre d'hydroxyles se situant entre 20 et 280. On utilise cette composition pour fabriquer des compositions de polyol polymère présentant les caractéristiques combinées suivantes: (a) une teneur élevée en polymères, de l'ordre de 30 à 60 %, (b) des viscosités faibles, typiquement inférieures à 9000 centipoises, (c) une stabilité de produit telle que 100 % de la composition passe à travers un tamis 150, et (d) un passage, à travers un tamis 700, des solides polymères contenus, pouvant aller jusqu'à 100 %.
