Outline of Research at the Start

高分子量の絡み合いポリスチレン (PS) メルト系では, 鎖の伸長・配向に伴って局所摩擦が減少し, 伸長粘度は低下することが知られている。しかし, (1) この摩擦減少は絡み合いの有無や高分子の化学構造に依らない普遍的現象なのか, (2) 鎖の伸長に加えて回転も誘起する剪断場でも同様に摩擦が減少するのか, などの重要事項は不明であった。本研究では PS も含めた多種の高分子の非絡み合いおよび絡み合い系に対する伸長および剪断流動実験と理論解析を行い, 問い (1) および (2) に関する完全な知見を確立する。

Outline of Final Research Achievements

For the standard molecular model for unentangled polymers, i.e., Rouse model, the equation of motion was fully analyzed for general cases of flow-dependent local friction z, spring stiffness k, and Brownian force intensity B, with z and B exhibiting tensorial nonlinearities. The dielectric loss e" reflecting the end-to-end fluctuation of the chain as well as the diffusivity under flow and rheological properties (viscosity and first normal stress difference coefficient) were analytically expressed in terms of z, k, and B to reveal characteristic features under flow, for example, lack of dielectric mode broadening under flow occurring in the velocity direction but acceleration of the relaxation in that direction. These analytical expressions enable experimental evaluation of z, k, and B, thereby serving as the very fundamental basis of molecular understanding of nonlinear flow behavior of polymers.

Academic Significance and Societal Importance of the Research Achievements

本研究は, 非絡み合い高分子の非線形レオロジー挙動の分子論的基盤を世界に先駆けて構築したものである。特に, 本研究が高分子鎖の摩擦係数, 弾性強度, 熱揺動力強度を実験的に評価することを可能とし, 高分子物理学に大きな進展をもたらしたことは, 学術的に大きな意義を持つ。さらに、本研究の成果は, 高分子樹脂の成形加工性を制御する基盤となり, 現在社会に不可欠の高分子産業にも大きく貢献する。
