摘要：

Intrinsic viscosities of solutions of fractions of polyethylene terephthalate in o-chlorphenol, dichloracetic acid, phenol-tetrachlorethane and trifluoracetic acid have been obtained at 25°, 35°, 45° and 55°C. The variation of [η] with solvent depends on both molecular weight and temperature. Temperature coefficients of [η] are large, being positive for trifluoracetic acid and negative in other cases. Values of KM and a in the expression [η] = KMMa are given and compared with those obtained by other workers. There is evidence for association of polymer in dichloracetic acid. © 1968.
