The study presents the possibility to replace the 1,2,4-trichlorobenzene (TCB) for the analysis by gel permeation chromatography (GPC) of low-density polyethylenes (LDPE) with dibutoxymethane (DBM, butylal), a halogen free and less toxic solvent. The molecular weight distributions and the viscosity plots were measured for commercial LDPE samples solubilized in TCB, and DBM, using a GPC system with...
