IMPROVED PROCESS FOR THE POLYMERIZATION OF EPOXIDES |
摘要 |
Process for the polymerization of epoxides using as catalyst a double metal cyanide-type compound, characterized in that the process is carried out in the presence of at least… (a) one or more salts composed of at least bivalent metal ions and metal-free anions, having a solubility in water of at least 1 g/100 ml at 25 DEG C, and/or… (b) one or more no-metal containing acids of which a 0.1 N solution in water at 25 DEG C has a pH not exceeding 3. |
