摘要：

Size exclusion chromatograph with on-line single capillary viscometer and multi-angle laser light scattering have been used for characterization of narrow polystyrene standards in 1,2,4-trichlorobenzene at 140-degrees-C. Mass-average molar mass, intrinsic viscosity and radius of gyration have been determined. From these values Mark-Houwink parameters and radius of gyration dependence on molar mass have been calculated.
