Abstract
To improve the solubility and adhesion strength of diamine-quinone polymers, urethane group was introduced into the polymer backbone. Urethane group containing polymeric diamines(UDA) were prepared firstly by the decarboxylation of the NCO group in NCO terminated prepolymer obtained from the reaction of MDI and 1.6-hexandiol. The reaction mole ratio of NCO/OH was changed from 1.2 to 2.1 to increase the molecular weight of diamine. From the addition reaction of UDA and p-benzoquinone in THF or DMSO solvent, five kinds of urethane group containing diamine/quinone polymers(PUAQ) were prepared according to the diamine used. IR, NMR, UV-visible spectroscopy and GPC were used to characterize the molecular structure and molecular weight of UDAs and PUAQs. Thermal analysis of polymer by DSC and TGA were carried out according to the molecular weight differency. Also solubility test of UDA and PUAQ with 10 different solvents were carried out to predict the coacting property of the polymers.
용해성과 접착력을 향상하기 위하여 우레탄 그룹을 함유하는 디아민-퀴논 중합체를 합성하고 특성분석을 행하였다. 디이소시아네이트와 저분자량의 디올을 반응시켜 NCO말단 프리폴리머를 합성한 다음 NCO그룹을 아민으로 변화시켜 우레탄기를 함유하는 디아민을 제조하였다. 이때 NCO/OH몰 비율을 1.2에서 2.1까지 변화시켜 디아민 분자량을 변화시켰다. 이러한 디아민기를 함유하는 프리폴리머를 p-벤조퀴논과 반응시켜 디아민-벤조퀴논 중합체를 제조하였다. 중합체의 분석에는 분광분석기와 크로마토그래피를 이용하여 분자구조 분석과 분자량을 측정하였으며, 용해도와 열적 거동도 측정 검토하였다.
