Cyclization reaction products by the end-to-end ring closure of telechelic polystyrenes (PSs) with molecular weight of 47k and 380k in THF (good solvent) and also in cyclohexane (poor solvent) were characterized by SEC connected with multi-angle light scattering (MALS). By comparison of the SEC peaks of the monomeric rings from 47k-PSs in THF and cyclohexane, there is no essential difference both...
The second virial coefficients A 2 of ring polystyrenes with high purity in cyclohexane were measured by light scattering in the temperature range 27.0–34.5°C. The purity of four samples with M w of 16k, 42k, 110k and 570k was determined to be all over 96% by HPLC. It has been found that A 2 s of all the samples are definitely positive at the theta temperature of linear polystyrene,...
