发帖数: 3715 | 1 If my monomer (aromatic compound) has a very poor solubility in THF or
toluene, then how it can be polymerized? |

try polymerization at high temperature
it also depends on what kind of monomer and what kind of polymerization. |

发帖数: 3715 | 3 Thank you for your reply. The monomer is a multi-ring aromatic compound,
very difficult to dissolve in DMF at 80 oC.
I am currently trying a free radically polymerization process. |

other monomer

functional group of your monomer using a longer spacer,and also try to redue
the rigidity of your monomer structure.

发帖数: 3715 | 7 en,make sense. Previously this monomer has been successfully copolymerized
with styrene in a molar ratio of 50/50. I will try a living polymerization
to see what will happen.

but that is toxic... |
