Abstract :
Polystyrene-block-polyisoprene or PS-b-PI with 74 styrene and 230 isoprene units was prepared by anionic polymerization. The diblock formed cylindrical micelles with PI core and PS corona in a PS-selective solvent N,N-dimethylacetamide. Nanofibers with different crosslinking densities were obtained after PI core crosslinking with differing amounts of sulfur monochloride. The nanofibers were characterized by elemental analysis, FTIR, transmission electron microscopy, and light scattering.
