Abstract
Intrinsic viscosity-molar weight relations are reported for polystyren e in N-methylpyrrolidone (NMP) and NMP/LiBr solutions at 30, 45, 60, 7 5, 90 and 105-degrees-C. Also, Mark-Houwink constants K(THETA) and the unperturbed dimensions of the polystyrene chains at these temperature s are calculated by applying Stockmayer-Fixman extrapolations of the v iscosity/molar weight data. The use of in-line size exclusion chromato graphy and viscometry is shown to be a facile and accurate method for such studies.
