摘要：

Interfacial tensions (IT) between polyisoprene and polystyrene (PS) were measured by the sessile drop method at 433K. For a normal PS and a PS carrying a nitroxide end-group, the values of IT were 2.54 +/- 0.5 and 2.38 +/- 0.5 dyne cm-1 respectively. The close match of these values suggests that the nitroxide end-label has no strong affinity for the polyisoprene domain.
