Abstract
Solubility of a polymer in a solvent, which is the most important property for polymer fractionation, depends generally on the chemical structures of both polymer and solvent. The old rule “similia similibis solventur” (solubility results from similarity) may give useful hints to select solvents for a polymer. This can be seen for the most solvent/polymer pairs listed in Table A 3 in the Appendix. Sometimes however, this rule also fails and this is illustrated by the following example: Water is a good solvent for poly(vinyl alcohol); poly(vinyl acetate) (from which poly(vinyl alcohol) usually is derived) is soluble in ketones. However, methanol or ethanol are nonsolvents for poly(vinyl alcohol) but solvents for poly(vinyl acetate).
