Xylene is an effective solvent of PP [17] while acetone is very successful as a non-solvent because the polymer can be precipitated in the form of powder without the formation of gelling lumps.At elevated temperature, PP can be dissolved in nonpolar solvents such as xylene, tetralin and decalin.A good solvent for each of polyethylene & polypropylene is a mixture of TCB ” 1,2,4-trichlorobenzene” with few percent (0.015 %) BHT ” butylated hydroxytoluene”. Unfortunately, the temperature required for dissolution (of both polymers in the mixed solvent) is 160 oC.
