초록

용해성, 기계적 강도, 열적 특성이 우수한 polyamideimide(PAI)에 강클한 수소결합이 가능한 아미드기를 더욱 많이 도입하기 위하여, trimellitic acid anhydride(TMA)와 diphenylmethane-4,4'-diisocyanate(MDI)와의 중축할 반옹에 IPA(또는 TPA)를 공단량체로 사용하여 다양한 poly(amideimide-co-amide)를 제조하였다. 생성된 각 공중할체들의 화학구조분석과 아미드기의 조성 중가에 따른 분자량과 용액안정성 변화 그리고 열적 기계적 특성들을 조사결과, isophthalic acid(IPA)를 공단량체로 카응한 경우fl는 40mol%, terephthalic acid(TPA)의 경우에는 30mo1% 이상이 공중합체에 도입되면 분자량, 용해도 특성이 급격히 감소하였으나, 이보다 적은 량의 IPA (또는 TPA)가 공중합체내에 도입된 경우에는 용액의 분자량이 높 용액보관 안정성이 우수할 뿐만 아니라 이로부터 제조된 필름의 인장강도 또한 우수하였다. 그리고 측정된 구리와의 접착 강도는 예측한 바와 같이 아미드기의 도입에 따라 중가하는 경향을 나타내었다.

In order to increase hydrogen bonding ability of Polyamideimide (PAI) by incorporation of more amide moiety, poly(amideimide-co-amide)s with various compositions were prepared by copolycondensation of IPA (or TPA) and TMA as comcnomers with MDI. The chemical structure analysis by spectrometer and effects of comonomer composition on molecular weight, solubility, and the thermal and mechanical properties were investigated. It was found that the molecular weight and solubilities of the copolymers were decreased drastically when the content of IPA and TPA were exceeded 40 mol% and 30 mol%, respectively. However, high inherent viscosity of copolymer and good storage stability of the solution can be achieved when the content of comonomers were less than those, and the tensile strength of the polymer films were excellent. The adhesion properties of the copolymer were increased with increasing of amide contents in the copolymers as expected.
