摘要: Well-defined high molar mass poly(1,4-butadiene)-g-poly(e-caprolactone) (PBu-g-PCL) graft copolymers were prepared through the grafting-from route by combination of ring-opening metathesis polymerization (ROMP) and organocatalyzed (ROP). The synthesis relies on ROMP cis-4-benzyloxymethyl-3-hydroxymethylcyclobutene initiated ruthenium-based Grubbs’ catalysts followed ROP e-caprolactone hydroxyl side groups backbone using 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as catalyst. reported strategy provides PBu-g-PCL having a strictly poly(1,4-butadiene) with highest up to now (Mn > 106 g mol–1). Self-assembling properties resulting copolymer investigated small-angle X-ray scattering (SAXS) in toluene solution solid state.
