项目摘要

1.ラジカル交換反応による熱力学的架橋反応(研究計画D)昨年度、動的共有結合であるアルコキシアミン骨格のラジカル交換反応を利用した高分子反応を架橋反応に利用し、側鎖-側鎖間のラジカル交換反応によるゲル化反応系に成功した。本年度は、分子量、架橋点の定量的な評価による反応挙動の詳細な解析を行い、動的共有結合を利用した平衡高分子反応による架橋反応の実体の解明を試みた。本平衡高分子反応系における著しい濃度依存性と架橋点の相対量と分子量の相関関係は、分子運動性と分子内・分子間架橋反応の濃度依存性に基づいて説明した。化学量論比の制御による定量的な脱架橋は、高分子鎖の浸透圧斥力、エントロピー弾性や、エンタルピー的凝集力に起因する架橋構造の熱力学的不安定性に基づき説明した(雑誌論文2,3)2.主鎖型動的共有結合ポリマーの主鎖交換反応による複合化と力学物性評価昨年度までに、主鎖型の動的共有結合ポリマーの創製と、加熱時におけるアルコキシアミン骨格のラジカル交換反応による複合化に成功している(研究計画B、C)。NMR測定などの分光学的手法や、力学物性評価により複合化状態の評価を行ったところ、ラジカル交換反応による主鎖レベルでの複合化により、異種高分子鎖が相溶化状態となったポリマーアロイの調整が可能であることを明らかにした。本年度は、セグメント長が十分に長いポリ(ジメチルシロキサン)鎖とポリスチレン鎖をアルコキシアミン骨格のラジカル交換反応により複合化し、凝集構造、力学物性の変化、形態観察により複合化状態の評価を試みた。調整した複合化ポリマーは、高いセグメント間凝集力によりバルク状態において相分離構造を形成したが、一次構造の統計的な不均一性に起因した極めて不規則な相分離構造を形成した。現在、論文を投稿中である。

1. Last year, there was a joint effort in the field of mechanics (Research Project D). In the past year, we made use of the high molecular weight anti-mechanical mechanism to make use of the high molecular weight counter-mechanism. in the past year, we made use of the high molecular weight counterforce to make use of the high molecular weight counterforce to make use of the counteraction mechanism to make use of the successful countermeasure. This year's quantitative analysis of molecular weight, molecular weight and frame point of this year's temperature, molecular weight, and frame point, the analysis of the operation, the co-operation of the activity, and the combination of the balance of molecular weight and molecular weight were used to explain the performance of the system. This balanced polymer is characterized by its degree dependence, molecular weight, molecular weight and molecular weight. The chemical quantity theory compares the quantitative "off-shelf", "polymer" immersion "repulsion", "polymer" and "agglutination" of the chemical theory to the cause of the uneasy nature of the mechanics. The co-operation of the main type of action, the mechanical and physical properties of last year's operation, and the combination of the main type of action, the combination of mechanical and physical properties, and the combination of the main type of action, the combination of the main type of activity and the combination of the main type of operation, the main type of activity, the main type of action, the mechanical and physical properties of last year's operation, and the main type of action, the combination of mechanical and physical properties of last year, and the main type of action, the combination of mechanical and physical properties of last year, and of the main type of action, the combination of mechanical and physical properties, and that of the main type of action, the combination of mechanical and physical properties of last year's operation, and that of the main type of action. (study plan B, C). NMR determination of differential optical techniques, mechanical properties, optical properties, optical properties, mechanical properties, optical properties, mechanical properties, optical This year, the number of people in the world is very high. This year, they are very long-term. This year, they are very long-term. In the current year, they are very long-term. This year, the number of people in the world is very high. This year, the number of people living in the same year is very high. This year, they are very important this year. In the current year, the number of people living in the hospital is very high. In this paper, the cause of the heterogeneity of the statistics is analyzed, and the cause of the non-uniformity of the statistics is caused by the separation of the agglutination force and the agglutination force in the system. At present, I am in the process of submitting my manuscript.
