Solid state polymerization of pet/pc extruded blend: effect of reaction temperature on thermal, morphological and viscosity properties
A systematic study of solid state polymerization (SSP), concerning the melt extruded blend of poly(ethylene terephthalate)/polycarbonate (catalyzed PET/PC, 80/20 wt %), as a function of temperature range (180-190°C) for a fixed time (6 h) is presented. The materials obtained were evaluated by differential scanning calorimetry (DSC), thermogravimetry/derivative thermogravimetry (TG/DTG), optical microscopy (OM) and intrinsic viscosity (IV) analysis. After SSP, at all reaction temperatures, PETdoi:10.1590/0104-1428.1518 fatcat:z5ubwmmgvvf4ta2dzjnwmvqb3m
