研究概要	1.希薄溶液中での高分子の形態とダイナミックス高分子電解質のダイナミックスを交流電場下での動的光散乱法によって(早川)、また中性の屈曲性高分子の局所的な分子形態変化を蛍光偏光解消法によって(山本)調べた。また多糖アミロースの溶液中での分子形態を明確にした(則末)。2.高分子の均一濃厚系のダイナミックス高分子の濃厚溶液、融体及びネットワーク中でのダイナミックスを粘弾性測定(五十野)、誘電測定(足立)、あるいはシミュレーション(岩田)によって調べた。また無定形固体中での高分子の局所的な運動性を粘弾性・複屈折測定より調べた(尾崎)。3.高分子系における相分離構造とダイナミックス組成の異なる2種の2元ブロック共重合体及びジブロック共重合体と単独重合体の混合物中で起こるミクロ相分離とマクロ相分離の競合による特異的なモルフォロジーについての詳細な研究(橋本)、非相溶な高分子ブレンド系の粘弾性に関する動的スケーリング則の適用性について(野田)研究した。また高分子/モノマー混合物系における重合反応に伴う相分離過程(野瀬)、外部電場下での高分子ブレンド系の相分離過程(太田)について調べた。4.界面における高分子の振舞い 3元ブロック共重合体の表面吸着層構造について原子間力顕微鏡等により(小高)、また高分子溶液中に懸濁させたシリカ粒子への高分子の吸着を粘弾性測定により(川口)調べた。さらに界面に吸着した屈曲性高分子、棒状高分子、及びブロック共重合体の形態について理論的な研究を行った(塩川等)。5.高分子ゲルの構造とダイナミックス化学架橋ゲルの膨潤溶媒中での変形に伴う膨潤及び応力の緩和現象について実験と理論の比較を行った(升田)。ポリスチレン/二硫化炭素系で起こる物理架橋ゲルのゲル化機構を中性子小角散乱法により調べた(和泉)。さらに2成分高分子ブレンド、及び2元共重合体/選択溶媒系中で起こる物理ゲルの熱力学的性質について理論的な研究を行った(田中、大野)。
