Abstract
Novel adhesive polyaspartamides containing catechol and primary amine pendent groups were synthesized through successive ring-opening aminolysis reactions of dopamine (DOP) and ethylenediamine (EDA) with polysuccinimide (PSI). The oxidative gelation of aqueous dopamine-modified polyaspartamide was observed by adding NaIO4 as the oxidizing reagent. FTIR, UV-vis and oscillatory rheometry was used to elucidate the oxidative cross-linking toward gel formation. The prepared gel was characterized by the swelling degree, thermogravimetric analysis (TGA), and by scanning electronic microscopy (SEM).

도파민 및 에틸렌디아민의 폴리숙신이미드(polysuccinimide) 와의 연속적인 개환 아미놀리시스 반응을 통해 카테콜및 1차 아민기를 곁가지에 함유한 접착성 폴리아스팔트아미드를 합성하고, 산화제로서 NaIO4를 사용한 상기 고분자 수용액의 산화적 젤화 반응을 관찰하였다. FTIR, UV-vis과 oscillatory rheometry를 이용하여 산화성 가교반응을 통한 젤형성을 규명하고, 제조된 젤의 수팽윤도, 열중량분석(TGA) 및 SEM 모폴로지를 조사하였다.
