초록

폴리(4-비닐피리딘)의 질소 원자에 메틸기를 부착시켜 4차아민화시켜서 부분적으로 개질된 폴리(4-비닐피리딘)을 얻었고, 부분 개질된 폴리(4-비닐피리딘)의 구조를 수용액상에서 레이저 광산란 및 형광법 등을 이용하여 조사한 결과, 자기 응집현상에 의하여 핵-껍질 구조를 가지고 있는 것으로 나타났다. 즉 사슬의 소수성 부분은 상호작용에 의하여 중심부에 모여있고, 4차화된 아민의 양전하를 가진 친수성 부분은 바깥껍질을 형성하고 있었다. 이 고분자 수용액에 음이온 계면활성제인, 도데실 황산 소듐을 첨가하면 이들 사이에 임계 응집 농도가 존재하며, 이 임계 응집 농도는 특히 NaCl 농도 0.1 M 이상에서는 급격히 감소하는 경향을 보여주었다. 또한 계면활성제의 첨가에 따라 생성된 고분자-계면활성제의 복합 응집체의 입자 크기 변화등을 동적 광산란으로 측정 분석하였다.

Modified poly(4-vinylpyridine) was obtained by partial quarternization of nitrogen atoms in pyridine rings of poly(4-vinylpyridine) with methyl group. By means of laser light scattering and fluorescence, it was found that this modified polymer chains were aggregated in the aqueous solution and its structure was coreshell type. The hydrophobic parts of the chains were densely condensed in core part and the hydrophilic part of quarternized amine with positive charge formed the shell part. In the mixed system of modified poly(4-vinylpyridine) and anionic surfactant, sodium dodecyl sulfate, it was observed that a critical aggregation concentration existed and that this critical concentration was suddenly decreased above 0.1 M NaCl. The size change of aggregates was also investigated by dynamic light scattering while sodium dodecyl sulfate was added into polymer solution upto the critical aggregation concentration.

Keywords:quarternized poly(4-vinylpyridine);sodium dodecyl sulfate;critical aggregation concentration;hydrophobic interaction;dynamic light scattering
