  • Process for producing polyether-polyester block copolymer
    Patent number: 8779084
    Abstract: The present invention discloses a process for producing a polyether-polyester block copolymer with a di(C 1-C 4)alkyl ester of aromatic dicarboxylic acid, an aliphatic diol or aliphatic polyol and a polyether having at least one terminal hydroxyl group in an inert solvent. In the present invention, the inert solvent 5 is used to prevent the di(C 1-C 4)alkyl ester of aromatic dicarboxylic acid from sublimation instead of excessive polyol, such that the subsequent removal of excessive polyol under high temperature and high vacuum is avoided.
