摘要: The following block–comb/graft copolymers of styrene (S), isoprene (I), and butadiene (B)—PS-b-(PB-g-PB), PS-b-(PB-g-PB)-b-PS, (PB-g-PB)-b-P2VP, (PS-g-PB)-b-(PI-g-PS), (PS-g-PB)-b-(PI-g-PS)-b-(PB-g-PI), (PS-g-PB)-b-(PI-g-PS)-b-(PB-g-PI)-b-(PI-g-PS)-b-(PS-g-PB), (PS)2(PB-g-PB) [where PS is polystyrene, PB polybutadiene, P2VP poly(2-vinylpyridine) (2VP), PI polyisoprene]—were synthesized with the macromonomer strategy anionic polymerization high-vacuum techniques. synthetic approach involves synthesis block copolymerization styrenic macromonomers in situ without isolation. prepared samples were characterized by size exclusion chromatography a differential refractometer detector, two-angle laser light scattering NMR spectroscopy. © 2005 Wiley Periodicals, Inc.
