- W313248727 abstract "研究了取代茚基二价稀土配合物(C5H9C9H6)2Yb(THF)2作为单组分催化剂,催化DMAEMA/MMA的共聚反应。结果表明,(C5H9C9H6)2Yb(THF)2对DMAEMA/MMA的共聚反应具有较高的催化活性,温度对共聚反应影响明显,单体配比对共聚反应的转化率影响不大,几种取代茚基二价稀土配合物都显示出较高的催化活性。其活性次序为:(C5H9C9H6)2Sm(THF)〉(C2H5C9H6)2Sm(THF)2〉(C5H9C986)2Yb(THF)2〉KSm(C5H9C9H6)3(THF)3〉(PhCH2C9H6)2Sm(THF)2。对聚合产物进行了热分析的表征,发现产物为两种单体的无轨共聚物。通过核磁共振技术确定了共聚物中两种单体所占的比例,并测定了(C5H9C9H6)2Yb(THF)2催化DMAEMA/MMA的共聚反应的竟聚率,其竟聚率为r1=0.98,r2=0.71。" @default.
