Reaction Steps
Polymerization reaction of tert-butyl 5-norbornene-2-carboxylate, Monomer 1, and maleic anhydride was effected using 2,2′-azobis(2,4-dimethylvaleronitrile) as the initiator, yielding an alternating copolymer of tert-butyl 5-norbornene-2-carboxylate/α-[hydroxy(5-norbornen-2-yl)methyl]-γ-butyrolactone/maleic anhydride (copolymerization ratio 4/1/5).
