DOI: dx.doi.org/10.14314/polimery.1980.135

Summary

The conditions of cryometric determination of molecular weight of polyterephthalates have been established. As solvent acenaphthene, m. p. 95°C has been used. Determinations have been carried out under argon. The system proposed could be used in the case of poly(decamethylene terephthalate). This system is of no use for polyethylene terephthalate) and poly(hexamethylene terephthalate) because of a too big differences in their solubility parameters and that of the solvent.
