Polystyrene solubility in toluene
WebPANI-salt, polyaniline doped with dodecylbenzenesulfonic acid (DBSA), was obtained by the emulsion polymerization in nonpolar organic solvent, toluene. In this study DBSA was used as a dopant along with a surfactant. PANI-salt and high impact polystyrene (HIPS) have a good solubility in toluene. WebStickiness can also arise from cohesive forces within the material. The polymer molecules prefer to stick together rather than spread onto a surface and thus adhere to something …
