초록

우레탄기를 함유한 고분자량의 디아민을 사용하여 유연성을 향상시킨 벤조퀴논/디아민 중합체를 합성하고 그에 따른 특성분석을 행하였다. 먼저 고분자량의 디아민은 평균 분자량이 750∼2000 사이의 3종의 서로 다른 폴리올을 MDI와 반응시켜 NCO-Prepolymer를 합성한 다음 말단의 NCO기를 아민화시켜 제조하였다. 폴리올류로는 옥시 알킬기 구조가 서로 다른 PPG, PTMG 및 PTMCG를 사용하였으며 NCO:OH의 반응 몰비는 2.1:1로부터 1.4:1까지 다양하게 변화시켜가며 합성하였다. 벤조퀴논:디아민의 몰비는 3:1로 고정하여 분자구조와 분자량이 각기 다른 9종의 퀴논/디아민 중합체를 합성하였으며 각각의 중합체에 대하여 구조분석, 열분석 및 분자량분석과 용해도측정을 행하였다. 아울러 이들 중합체와 NCO-Prepolymer를 반응시켜 가교된 퀴톤/디아민 중합체를 합성하여 각각의 함수율과 XRD분석을 통해 분자량 변화에 따른 결정성 및 UTM을 통한 기계적 물성도 고찰하였다.

Benzoquinone/diamine polymers were synthesized from reaction of flexible polymeric diamines containing urethane group with p-benzoquinone. Polymeric diamines were obtained from the decarboxylation of NCO-terminated prepolymer prepared by the reaction of MDI and polyols with average molecular weight range of 750 ∼2000. PPG, PTMG, PTMCG with different molecular structure and molecular weight were used as polyols and reaction mole ratio of NCO : OH were changed from 2.1 : 1 to 1.4 : 1 for NCO-terminated prepolymer preparation. And quinone/diamine polymers were prepared by the reaction of 1 mole of diamine with 3 mole of p-benzoquinone. For these 9 different quinone/diamine polymers, characterization of molecular weights, solubilities, thermal properties and molecular structure were carried out. Additionally, crosslinked quinone/diamine polymers were synthesized from reaction of quinone/diamine polymers with NCO-Prepolymer. The effects of molecular weights of crosslinked polymers on the degree of water absorption, crystallinity and mechanical properties were investigated.
