Title
(EN) PROCESS MAKING POLYMER POLYOL HAVING MONODISPERSE DISPERSED POLYMER PARTICLES
(FR) PROCÉDÉ DE FABRICATION DE POLYOL POLYMÈRE DOTÉ DE PARTICULES DE POLYMÈRE DISPERSÉES MONODISPERSÉES
Abstract
(EN)
Polymer polyols are made in a seeded process, in which styrene and acrylonitrile are polymerized in the presence of a base polyol, a seed dispersion and a solvent. The seed dispersion contains an unsaturated macromer. The process produces a polymer polyol in which the dispersed phase particles have a particle size of 1 to 3 μm and a particle size span of less than 1.25. The polymer polyols are very useful for making flexible polyurethane foam for cushioning applications, in which high airflows and good load bearing are needed.
(FR)
L’invention concerne des polyols polymères fabriqués par un procédé amorcé, dans lequel du styrène et de l'acrylonitrile sont polymérisés en présence d'un polyol de base, d'une dispersion d’amorce et d'un solvant. La dispersion d’amorce contient un macromère insaturé. Le procédé produit un polyol polymère dans lequel les particules de phase dispersée ont une taille de particule de 1 à 3 µm et une étendue granulométrique inférieure à 1,25. Les polyols polymères sont très utiles pour fabriquer une mousse de polyuréthane souple destinée à des applications d'amortissement, dans lesquels des flux d'air élevés et un bon support de charge sont nécessaires.
