Title (EN) POLYMER POLYOL COMPOSITIONS HAVING GRAFTED UNSATURATED ACID SALT AND THEIR USE IN THE PREPARATION OF POLYURETHANE FOAMS
(FR) COMPOSITIONS DE POLYOL POLYMERE COMPORTANT UN SEL D'ACIDE INSATURE GREFFE ET UTILISATION DE CES COMPOSITIONS POUR PREPARER DES MOUSSES DE POLYURETHANNE
Abstract:
(EN) A process for the preparation of a polymer polyol having grafted ethylenically unsaturated acid salt comprising the following steps: (a) $i(in situ) polymerization of an ethylenically unsaturated acid in a polyol having a hydroxyl number from 15 to 80 in the presence of a free-radical polymerization initiator; (b) $i(in situ) polymerization of an ethylenically unsaturated monomer or a mixture of ethylenically unsatured monomers in the product obtained in step (a) in the presence of a free radical polymerization initiator; and (c) neutralization of a product obtained in step (b) with an alkali metal or alkaline earth metal hydroxide or alkoxide is disclosed. Polymer polyols having grafted an ethylenically unsaturated acid salt prepared by the disclosed process are used to produce a fire retardant, low fogging, flexible polyurethane foam.
(FR) Procédé pour préparer un polyol polymère comportant un sel greffé d'acide insaturé en éthylène. Ce procédé comprend les étapes suivantes: (a) polymérisation $i(in situ) d'un acide insaturé en éthylène pour former un polyol avec un nombre hydroxy allant de 15 à 80, en présence d'un amorceur de polymérisation radicalaire; (b) polymérisation $i(in situ) d'un monomère insaturé en éthylène ou d'un mélange de monomères insaturés en éthylène dans le produit obtenu dans l'étape (a), en présence d'un amorceur de polymérisation radicalaire; et (c) neutralisation du produit obtenu dans l'étape (b) avec un hydroxyde ou un alcoxyde de métal alcalin ou de métal alcalino-terreux. Les polyols polymères comportant un sel greffé d'acide insaturé en éthylène, obtenus par ce procédé, sont utilisés pour produire une mousse de polyuréthanne ignifuge, flexible, à faible nébulisation.
