发帖数: 146 | 1 I use AESH (cysteamine0 as the chain transfer agent to synthesize PNIPAAM.
Is there anyone know what is the diference if I use AESH or AESH`HCl? I
want to synthesize 2000-3000 MW PNIPAAm, I use 0.05 [S]/[M], why the MW is
10000? it seem so high, why? Thank you | o*8
发帖数: 6 | 2 你有什么方法测的MW？不同的测试方法之间也有误差的。
文献上也是有这个比例做的？结果是2－3k？你确定用这个比例一定可以得出这个分子
量？
如果你只是想得到2－3K的，增大比例就是了。
