Patent ID: 7423112

Claim:
A process for preparing polyether polyols containing pendant amine groups comprising: (A) reacting (a) an organic compound containing from 1 to 10 hydroxyl groups and having a molecular weight of from about 32 to about 15,000, with (b) one or more epoxides wherein at least one epoxide contains one or more halogen atoms, in the presence of (c) one or more double-metal cyanide catalysts, to form a polyether polyol containing halogenated carbon atoms having a molecular weight of from about 120 to about 25,000 and containing from about 1 to about 10 hydroxyl groups; and (B) reacting (a) the resultant polyether polyol containing halogenated carbon atoms formed in (A), with (b) an amine group containing compound having from 1 to 3 amine groups and a molecular weight of from about 17 to about 500, wherein said amine groups are selected from the group consisting of primary amine groups, secondary amine groups, tertiary amine groups and mixtures thereof, thereby forming a polyether polyol having a molecular weight of from 105 to 35,000, and containing at least one terminal hydroxyl group and at least one pendant amine group.
