  • Polymerization of alkylene oxides onto functionalized initiators
    Publication number: 20040266982
    Abstract: Certain alcohol initiators containing halogen, aldehyde, ketone or nitro substitution can be alkoxylated with excellent efficiency and low production of by-products using an metal cyanide catalyst. The products contain halogen, aldehyde, ketone or nitro groups that can undergo subsequent reactions to form amino groups.
