PH-SENSITIVE POLY ASPARTAMIDE GRAFT COPOLYMER CONTAINING THE IMIDAZOLE GROUPS AND PREPARATION THEREOF

摘要

PURPOSE: A potential for hydrogen(pH)-sensitive poly aspartamide graft copolymer, and a manufacturing method thereof are provided to simply manufacture the copolymer with the graft reaction, and to secure the harmlessness to the human body. CONSTITUTION: A pH-sensitive poly aspartamide graft copolymer is formed with a recurring unit marked with chemical formula 6, and has the molecular weight of 34,000~53,000. A manufacturing method the pH-sensitive poly aspartamide graft copolymer comprises a step of adding octadecylamine, 1-(3-aminopropyl)imidazole, and O-(2-aminoethyl)-O'-methylpolyethylene glycol to polysuccinimide.
