| titleOfInvention | A Novel Temperature/pH Dual Sensitive Polyaspartic Acid Derivative |
| abstract | The present invention provides a novel temperature/pH dual sensitive polyaspartic acid derivative, the molecular formula of the polyaspartic acid derivative is (C 9 H 16 N 2 O 3 )n, where n is temperature/pH dual The degree of polymerization of the sensitive polyaspartic acid derivative, n is an integer of 40-500. The main chain of the novel temperature/pH dual-sensitive polyaspartic acid derivative is polyaspartic acid, the side chain is an ethoxypropylamine group, and the side chain and the main chain are combined with an amide bond. In the present invention, polyaspartic acid is used as the main chain structure to ensure that the main structure has good biological safety and degradability, and ethoxypropylamine group is selected as the side chain and connected to the main chain of polyaspartic acid by an amide bond, Its side chain is single, the structure is regular, the relationship between structure and performance is clear, it is safe and biodegradable, and it is temperature sensitive. There is no problem of performance fluctuation caused by the irregular distribution of various side chain structures. its transition temperature. |
