Title: | Analysis of the molecular weight distribution of polystyrene | Authors: | Radičević R. Kisin S. Krakovsky I. |
Issue Date: | 1-Jan-2004 | Journal: | Chromatographia | Abstract: | In this paper are reported molecular weight distributions (MWD) of polystyrenes obtained by bulk free-radical polymerization of styrene under isothermal conditions. MWD of polystyrenes were determined by gel-permeation chromatography. From analysis of the results it is apparent that samples synthesized at 80°C and 90°C have a bimodal MWD whereas those obtained at 100°C and 110°C have unimodal MWD. By two-peak deconvolution of experimental curves (at 80°C and 90°C) it is possible to separate the contribution of polystyrene obtained before and after onset of the gel effect. | URI: | https://open.uns.ac.rs/handle/123456789/11419 | ISSN: | 00095893 |
