Hi Stefano, As far as I know, chlorinated organic products, such as methylene chloride and chloroform, are good solvents for polycarbonate. In particular, methylene chloride can be a good candidate, since the intrinsic viscosity values for PC are usually given using this solvent or dioxane, which could be another alternative.

Does anyone know the company that sells lower Mw of PC? And I have a problem when I make a solution with Toluene or PGMEA Does anyone know good solvent for PC solution?
