Research Abstract |
リビング重合による末端官能基化ポリマーの合成と得られたポリマーのクリック反応によりポリヘキシルイソシアネートと生分解性ポリマー(ポリ乳酸やポリカプロラクトンなど)を含んだブロックおよび星型共重合体を精密合成し、得られたブロックおよび星型共重合体の自己組織化とポリヘキシルイソシアネート部分の選択的なエッチングにより生分解性ナノポーラス材料を作る簡便精密合成法を確立した。 1230350EB001 Facile method on precise synthesis of biodegradable nanoporous polymer materials was developed by the following procedures; 1) living polymerization leading to end- functionalized polyisocyanate and biodegradable polymer (polylactic acid and polycaprolactone, etc), 2) click reaction between the obtained end-functionalized polymerleading to block and star copolymers, 3) self-assembly of the obtained block and star copolymers, and 4) selective etching of polyisocyanate parts leading to biodegradable nanoporous polymer materials.
