| titleOfInvention | A kind of preparation method of polyetherester random copolymer based on polyethylene furandicarboxylate |
| abstract | The invention relates to the field of polymer synthesis, and discloses a preparation method of a polyetherester random copolymer based on polyethylene furandicarboxylate. Formic acid diester and ethylene glycol are polymerized monomers, and under the action of a polybasic organic sulfonic acid catalyst and an organic metal catalyst, esterification-etherification and polycondensation are carried out in sequence to obtain a polyetherester random copolymer. Wherein, through the regulation of catalyst content, the content of diethylene glycol chain segment in the polyetherester random copolymer is 5-80 mol%. The method of the invention can synthesize polyetherester efficiently and environmentally by a one-pot method without adding a third monomer, using a low-added polyvalent organic sulfonic acid catalyst and an organometallic catalyst as a composite catalyst, and the polyetherester The content of diethylene glycol chain units in the copolymer can be adjusted in a wide range, and it has excellent thermodynamic properties and gas barrier properties. |
