| titleOfInvention | Preparation method of furan bio-polyether ester copolymer and novel furan bio-polyether ester copolymer |
| abstract | The invention provides a preparation method of a polyether ester copolymer, which comprises the following steps of carrying out esterification reaction on 2, 5-furandicarboxylic acid and ethylene glycol under the conditions of protective atmosphere and a metal complex catalyst, and then carrying out pre-polycondensation reaction and polycondensation reaction to obtain the polyether ester copolymer. The invention can efficiently prepare the furan full-biobased polyether ester copolymer with high viscosity and novel structure by directly carrying out polycondensation reaction on FDCA and biobased ethylene glycol under the catalysis of a metal complex catalyst and by adopting a simple synthesis means at a lower temperature within a shorter time, and the molecule of the furan full-biobased polyether ester copolymer contains an oligoethylene glycol chain segment with controllable content, so that the reaction process is stable, easy to control and mild in condition, and the preparation method is economic and environment-friendly and is suitable for large-scale industrial production. The furan bio-polyether ester copolymer product provided by the invention has a high-content glycol chain segment in the structure, and has good thermodynamic property and good color. |
