cyclohexane is not good solvent for PS. if you have prepared PS and put it into cyclohexane, PS will not dissolve. Therefore, during the polymerization, PS will dissolve in cyclohexane. but it also depends on the molecular weight of PS. if PS; Mw is too large, it will not dissolve in cyclohexane. |
