| abstract |
The present invention relates to a process for producing a copolyetherester polyalcohol having a low oligomeric polyether ether content of, for example, less than about 2.0% by weight, which comprises a low number average molecular weight having, for example, 350 g/mol or 350 g/mol or less and For example, a feed of about 0.4% by weight or more of a high oligomeric polyether ether content of polytetramethylene ether glycol is produced. |
