Keywords: | Multi-detector size exclusion chromatography | Issue Date: | 2006 | Citation: | European Polymer Journal. 42:4 (2006) 751-763 | Abstract: | This work reports the utilization of a multi-detector size chromatography for the characterization of poly(vinyl chloride) (PVC) resins prepared by suspension polymerization in the range of temperatures between 21 and 75 °C. The chromatography equipment offers the possibility of analyzing the samples in terms of their absolute molecular mass using a combination of three detectors (TriSEC): right angle light scattering (RALLS), a differential viscometer (DV) and refractive index (RI). The PVC resins were fully characterized concerning the molecular weight distribution (MWD), its dependence with intrinsic viscosity ([eta]) and molecular sizes (radius of gyration, Rg and hydrodynamic radius, Rh). Additionally, it is also presented the characterization of polystyrene narrow standards serving as reference polymers. | URI: | https://hdl.handle.net/10316/3794 | DOI: | 10.1016/j.eurpolymj.2005.09.023 | Rights: | openAccess |
