发帖数: 146 | 1 I synthesized PLA-PEG-PLA (2.5k-5k-2.5k) by ROP in toluene , but the
products
did not disslove in CH2CL2 nor DMF. The solution is like semitransparent
milk,
which brought the problems to do next step. Is it normal for the
solubility?

weights, how many dichloromethane did you use to dissolve? | s*****i

for DCM, you need to dilute, let's say, try dissolve them in 50ml of DCM
gram by gram with vigorous stirring. It may be time-consuming, however, that
's the efficient way to try solubility of macromolecules.good luck
