| titleOfInvention | Photochromic polyester and preparation method and application thereof |
| abstract | The invention discloses photochromic polyester and a preparation method and application thereof. The photochromic polyester has the following structure: R m and R n Are independently selected from H, F, Cl, Br, I, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, nitro, methoxy and the like, m is an integer of 1-4, n is an integer of 5-8, p is 20-200, q is 20-200, R is a Is the residue of an aromatic diacid. The preparation method comprises the following steps: the photochromic polyester is prepared by copolymerizing aromatic diacid compound or esterified compound thereof with azobenzene compound and other dihydric alcohol. The photochromic polyester prepared by the invention has response speed of less than 20 seconds, has good mechanical strength and flexibility, rapid photochromic speed and mechanical property, and has great potential application significance in information storage elements and self-development holographic recording photographic materials in order to promote the development of thermoplastic polyester functionalization. |
