Title
(EN) HIGHLY ACTIVE DOUBLE METAL CYANIDE CATALYSTS
(FR) CATALYSEURS A HAUTE ACTIVITE A BASE DE CYANURE METALLIQUE DOUBLE
Abstract
(EN)
Highyl active double metal cyanide (DMC) catalysts are disclosed. The catalysts comprise a DMC complex, and organic complexing agent, and from about 5 to about 80 wt.%, based on the amount of catalyst, of a polyether having a number average molecular weight less than about 500. The catalysts polymerize propylene oxide at a rate in excess of about 1 kg PO/g Co/min. at 100 ppm catalyst, based on the weight of finished polyether, at 105 °C. The catalysts, which are easy to prepare, give polyether polyols with exceptionally low unsaturation levels.
(FR)
L'invention concerne des catalyseurs à haute activité à base de cyanure métallique double (DMC). Ces catalyseurs comprennent un complexe DMC, un agent complexant organique, et environ 5 à 80 % en poids, par rapport à la quantité de catalyseur, d'un polyéther ayant un poids moléculaire moyen en nombre inférieur à environ 500. Les catalyseurs polymérisent l'oxyde de propylène à une vitesse supérieure à environ 1 kg PO/g Co/mn pour 100 ppm de catalyseur, par rapport au poids du polyéther fini, à 105 °C. Les catalyseurs, qui sont faciles à préparer, donnent des polyéther polyols dont les niveaux d'insaturation sont exceptionnellement faibles.
