Outline of Final Research Achievements

It is expected that steric information can be transferred by polymerization of acrylic acid connect to polyvinyl alcohol by ester-bond. As a model, 2,4-pentanediol can be regarded as a dimer of polyvinyl alcohol and its acrylic diester was prepared. A literature search was conducted on the polymerization reaction conditions of the obtained diester. In addition, the structure of polyallylamine was analyzed by NMR. Some signals of hydrochloride of the polymer were observed broadly, suggesting the presence of isomers. DOSY measurement of an aqueous solution of the polymer salt having a molecular weight of 10000 revealed that it was a mixture of a polymer and a monomer.

Academic Significance and Societal Importance of the Research Achievements

各モノマーを逐次的に付加伸長して得られるブロック共重合体では、モノマーの位置、分子量が制御されている。すなわち本研究で取得を目指すブロック性はすでに合成時で情報が与えられている。一方、プロセスが煩雑になる分、製造コストや技術的ハードルはランダム共重合体に比較すると高くなる。したがって安価かつ容易に製造できるランダム共重合体におけるブロック性の情報が取得できることは共重合体の構造と物性、機能を紐づける重要な情報となり、学術的だけでなく、産業的にも大きな波及効果をもたらすと考える。
