| titleOfInvention | Tartaric acid group optical activity polyamide and preparation method thereof |
| abstract | The invention discloses tartaric acid optical rotation polyamide PAm L AT and a preparation method thereof, belonging to the technical field of functional polymer materials, wherein the structure general formula is as follows: (m =4,5, 7-14). The polymer uses L-2, 3-diacetyl oxygen tartaric acid (L-ATA) as raw material, uses solid phosgene (BTC) as chlorination reagent, L-ATA is processed through acyl chlorination reaction to prepare L-2, 3-diacetyl oxygen succinyl chloride (L-ATC), then uses L-ATC and aliphatic diamine as monomers, and adopts interfacial polymerization method to prepare polyamide PAm L AT. with higher molecular weight and stronger optical activity. |
