The complete steady-state flow properties of molten poly(ethy1ene terephthalate) for shear stresses 34.14 X 1CP dynes/cm\* were determined. A single, complete master curve had been constructed in earlier work by Gregory and Watson; the curve interrelates the shear stress, shear rate, temperature, an
## Abstract The depolymerization of poly(trimethylene terephthalate) (PTT) in supercritical methanol was carried out with a batchβtype autoclave reactor at temperatures ranging from 280 to 340Β°C, at pressures ranging from 2.0 to 14.0 MPa, and for reaction time of up to 60 min. PTT quantitatively de
