| titleOfInvention | Low-hygroscopicity PA5T and synthesis method thereof |
| abstract | The invention provides PA5T with low hygroscopicity and a synthesis method thereof, wherein perfluoroadipic acid is introduced as a comonomer in the synthesis process of PA5T, so that a polyamide molecular chain is provided with a certain amount of fluorine-containing chain segments, the low surface energy characteristic of the low surface energy is capable of endowing PA5T with hydrophobicity, the hydrolysis resistance of PA5T is improved on the basis of reducing the hygroscopicity of PA5T, and the water absorption of the obtained PA5T material is reduced to below 1%. The hypophosphite and pyridine are used as catalysts, so that the fluorine-containing chain segment is more easily and uniformly dispersed on the PA5T molecular chain segment, and the hydrolysis resistance of PA5T is improved. |
