| titleOfInvention | Bio-based copolyester with high heat resistance, high barrier and UV resistance and its preparation method and application |
| abstract | The invention discloses a bio-based copolyester with high heat resistance, high barrier and ultraviolet resistance, and a preparation method and application thereof. The preparation method includes: reacting a first mixed reaction system comprising a first component, a second component, a third component, and a fourth component with an esterification catalyst and/or a transesterification catalyst under a protective atmosphere , to obtain an intermediate product; the first component includes any one or a combination of two or more selected from furandicarboxylic acid, furandicarboxylic acid esters, thiophenedicarboxylic acids, and thiophenedicarboxylic acid esters, and the second group The components include bio-based anti-ultraviolet diacids and/or bio-based anti-ultraviolet diacid esters, and the fourth component includes dihydric alcohols; and, under vacuum conditions, the intermediate product is subjected to a polycondensation reaction to obtain high heat resistance High barrier UV resistant biobased copolyester. The high heat-resistance, high-barrier, and ultraviolet-resistant bio-based copolyester prepared by the invention has excellent ultraviolet shielding performance, heat resistance and barrier property, and has wide application prospects in packaging materials. |
