Abstract
Description
NMR分析は、三重共鳴5mm探針(probe)を有するVarian Unity Inova(500MHz)分光計を含むNMR分光計を使って常温で遂行した。NMR測定用溶媒(CDCl3)に分析対象物質を約10mg/ml程度の濃度に希釈して使用したのであり、化学的移動はppmで表現した。
br=広い信号、s=単一線、d=二重線、dd=二重の二重線、t=三重線、dt=二重の三重線、q=四重線、p=五重線、m=多重線。
数平均分子量(Mn)および分子量分布は、GPC(Gel permeation chromatography)を使って測定した。5mLバイアル(vial)に実施例または比較例のブロック共重合体またはマクロ開始剤などの分析対象物質を入れ、約1mg/mL程度の濃度となるようにTHF(tetrahydro furan)に希釈する。その後、Calibration用標準試料と分析しようとする試料をsyringe filter(pore size:0.45μm)を通じて濾過させた後測定した。分析プログラムは、Agilent technologies社のChemStationを使用したのであり、試料のelution timeをcalibration curveと比較して重量平均分子量(Mw)および数平均分子量(Mn)をそれぞれ求め、その比率(Mw/Mn)で分子量分布(PDI)を計算した。GPCの測定条件は下記の通りである。
