Abstract
The present invention relates to a high molecular weight polymer having an aldaric acid as a constitutional unit, and a method for producing the same, and more specifically, relates to a thermoplastic polymer which comprises at least one repeating unit derived from an aldaric acid, and has a weight average molecular weight of 3,800 or more.
Claims16
A thermoplastic polymer comprising at least one repeating unit derived from an aldaric acid and having a weight average molecular weight of 3800 or more.
A method for producing a polymer comprising a repeating unit derived from an aldaric acid, the method comprising:
- (i) mixing an aldaric acid or a derivative thereof, and a diamine or a diol in water and a non-polar organic solvent;
- and
- (ii) concentrating a reaction mixture obtained in step (i) under reduced pressure.
