Popis: Herein, we report the synthesis of a novel regioregular poly-norbornene anhydride-g-(3-hexyl thiophene) (PNBA-g-PHT) graft copolymer. Grignard metathesis polymerization was used to obtain a PHT homopolymer. Then, PHT-N3 was prepared via a chemical modification reaction of the hydroxyl terminated PHT. A click chemistry approach was then used to synthesis MM 1. Finally, ring-opening metathesis polymerization (ROMP) of MM 1 produced the final copolymer. NMR and COSY studies clearly showed that the regioregularity was retained in the newly synthesized copolymer.
