PREPARATION OF FUNCTIONALIZED POLYETERS. |
| abstract |
A hydroxyl-functional and unsaturation-functional polyoxyalkylene polyether, which has (a) no more than one initiator molecule per polyether molecule, and (b) no more than 0.020 meq / g of unsaturation apart from that of the unsaturation derived of the initiator molecule, preparable by: a) selecting an initiator molecule having a number average molecular weight below 500 Da, at least one carbon-carbon unsaturation site, and at least one functional group that is oxyalkylated by alkylene oxide in the presence of a double metal cyanide complex catalyst, wherein said initiator molecule has only one free carboxylic acid group; b) oxyalkylating said initiator molecule with one or more alkylene oxides in the presence of an effective amount of a double metal cyanide complex catalyst and under conditions effective to form such polyoxyalkylene polyether; and c) recovering a hydroxyl- and unsaturation-functional polyoxyalkylene polyether having (a) no more than one initiator molecule per polyether molecule, and (b) no more than 0.020 meq / g of unsaturation apart from unsaturation derived from The initiating molecule. |
