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

try polar solvents like DMF or DMSO
try polymerization at high temperature
it also depends on what kind of monomer and what kind of polymerization.

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.

sounds like steric effect plays a role and you might try copolymerize with
other monomer

how did u purify it? it has poor solubility in any solvent?

You may want to modifiy your monomer, re-link the vinyl group and pendant
functional group of your monomer using a longer spacer,and also try to redue
the rigidity of your monomer structure.

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.

maybe you can use benzene
but that is toxic...
