Embodiment 1

[0038] Add 200ml of phosphate buffer solution with a pH of 7 to a 250ml three-neck flask, then add polyvinylpolyamine and carboxymethyl-α-cyclodextrin into the flask at a molar ratio of 3:1, and react in a mixed ice-water bath After 24 hours, the modified cyclodextrin was precipitated with acetone as a solvent, and dried under vacuum at 100°C.

[0039] Completely dissolve 1 mol of cyclodextrin modified by polyethylene polyamine in 300ml of 50% ethanol / water solution, then make the molar ratio of cyclodextrin and polyethylene glycol 50:1, add polyethylene glycol 2000 and stir at 70°C After reacting for 16 hours, slowly cool down to room temperature, let it stand still, filter and wash after a large amount of precipitates appear, and vacuum dry to obtain the target product—polyethylene polyamine modified cyclodextrin and polyethylene glycol clathrate.

Abstract

The invention discloses an easily crystallizable furan-based polyester composition containing a polyethylene polyamine-modified cyclodextrin and ethylene glycol composite nucleating agent and a preparation method thereof. The furan-based polyester composition has the characteristics of high crystallinity and a fast crystallization speed, can shorten a molding period, can improve the performances,has simple processes and is easy to industrialize.

Description

technical field [0001] The present invention relates to the technical field of polymer materials, in particular to the technical field of a furan-based polyester material, in particular to a furan-based polyester containing polyethylene polyamine-modified cyclodextrin and ethylene glycol composite nucleating agent Compositions and methods for their manufacture. Background technique [0002] As a typical furan-based polymer, 2,5-furandicarboxylic acid-based polyester has excellent mechanical properties, electrical properties and low moisture absorption properties, and is a new type of engineering plastic with good comprehensive properties. However, due to the large steric hindrance of the furan ring on the main chain and the poor flexibility of the molecular chain, the crystallization rate is slow, which has a negative impact on the processing performance and physical and mechanical properties of furan-based polymers, and also reduces the efficiency of industrial production a...
