摘要：

Intrinsic viscosities [eta] in tetrahydrofuran (THF) at 30-degrees-C are reported for ten narrow molecular weight distribution poly(methyl methacrylate) (PMMA) samples covering nearly two orders of magnitude in molecular weight. By combining the viscosity results with absolute weight-average molecular weights (M(w)BAR) determined via low-angle laser light scattering (LALLS) experiments, we have accurately determined the Mark-Houwink-Sakurada (MHS) parameters for this polymer-solvent pair (K = 7.56 x 10(-5) and a = 0.731, when [eta] is in dL g-1).
